Description

Technical Field

[0001] This utility model belongs to the field of vehicle component technology, specifically relating to a protective structure for a motor liquid buffer radiator. Background Technology

[0002] Pure electric mining dump trucks generally work in open-pit mines with harsh and difficult environmental conditions. The roads in the mines are covered with gravel and are uneven, which makes the chassis and front parts of the vehicle susceptible to direct impact and collision from flying gravel or protruding obstacles during the driving process.

[0003] Currently, the radiators and related piping that provide cooling for the motor hydraulic retarder system are usually located directly in the front area of ​​the vehicle frame and lack effective protection, leaving them exposed to the external environment for extended periods.

[0004] This method is only applicable to ordinary road conditions. However, in mining areas, due to the lack of sufficient protection, the radiator and pipes are prone to structural damage under frequent impacts, which can lead to problems such as coolant leakage and failure of heat dissipation function, affecting the overall safety and reliability of the vehicle. Utility Model Content

[0005] The purpose of this invention is to provide a protective structure for a motor liquid buffer radiator, which solves the technical problem that the existing motor liquid buffer radiator and pipeline are easily damaged by impact due to direct exposure.

[0006] This utility model discloses a protective structure for a motor liquid buffer radiator, including: a lower protective assembly, two support frame assemblies and a front protective assembly, wherein the two support frame assemblies are respectively disposed on both sides of the rear end of the lower protective assembly, and the front protective assembly is disposed at the front end of the lower protective assembly; The lower protection assembly includes: The base plate is horizontally arranged. Two side plates are respectively located on both sides of the base plate and extend upward perpendicularly to the base plate, and the top center of the side plates is provided with a clearance notch; The support frame assembly includes: The L-shaped plate has a vertical section and a horizontal section. The lower part of the vertical section is attached to and fixedly connected to the rear end of the corresponding side plate. The horizontal section is located at the top of the vertical section and extends horizontally outward. Multiple reinforcing plates are spaced apart between the vertical section and the horizontal section; The front protective assembly includes: A front baffle is arranged vertically and extends along the width direction of the base plate; The inclined plate has its top edge connected to the bottom edge of the front baffle, its bottom edge abutting against the front end of the base plate, and its two sides connected to the front ends of the two side plates respectively.

[0007] This application forms a structurally robust overall frame that can effectively block impacts from gravel from the bottom, sides, and front, reducing the risk of damage to the motor hydraulic radiator and its piping. The open layout on both sides and the rear takes into account the heat dissipation requirements, and reliable installation is achieved through the support frame assembly and the vehicle frame.

[0008] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the front baffle has multiple vertically arranged elongated holes, which are arranged at horizontal intervals. This solution ensures the front protection effect and structural strength while providing an air intake channel for the rear motor liquid radiator, thereby improving heat dissipation efficiency. The holes also reduce the overall structural weight and improve the lightweight effect.

[0009] Preferably, the front protective assembly includes: Two connecting components are respectively located on the upper sides of the inner side of the front baffle. This solution achieves a rigid connection between the protective structure and the front bumper, effectively enhancing the overall structural strength and stability, preventing vibration or displacement due to road impact, and the detachable connection method facilitates the disassembly and maintenance of the protective structure, improving maintenance portability.

[0010] Preferably, the connection component includes: The mounting tube is horizontally positioned on the inner side of the front baffle. A threaded tube is fixedly sleeved inside the outer end of the mounting tube. This solution avoids stress concentration, ensures connection stability, and provides a precise, reliable, and wear-resistant threaded connection interface, improving the reliability and durability of the connection with the front bumper.

[0011] Preferably, the base plate is divided into an installation area, a transition area, and a connection area from front to back along its length. The width of the installation area is greater than the width of the connection area, and the width of the transition area gradually decreases from front to back. By adopting this solution, the structural shape of the base plate matches the actual layout of the radiator and the pipeline, providing comprehensive bottom protection for the radiator and targeted protection for the pipeline, while also simplifying the materials. Furthermore, it ensures all-round protection while taking into account lightweight and structural compactness.

[0012] Preferably, the lower protection assembly further includes: Two connecting plates are respectively perpendicularly disposed on the front end of the inner side surface of the two side plates, and the bottom edge of the connecting plate is connected to the front end of the bottom plate; The inclined plate is attached to two connecting plates on both sides and is detachably connected. This solution can effectively disperse and transfer the impact force on the inclined plate to the side plate and the bottom plate, and provides a connecting surface for the inclined plate. The surface has a large contact area and a stable connection, which ensures the stress on fasteners such as bolts.

[0013] Preferably, the base plate is provided with a loading and unloading port; this solution facilitates the installation and removal of the radiator drain valve by maintenance personnel, simplifies the maintenance process, improves work efficiency, and facilitates the full drainage of water accumulated on the base plate.

[0014] Preferably, the lower protection assembly further includes: Two sets of diagonal bracing plates are respectively vertically installed on both sides of the rear end of the top surface of the base plate. Each set of diagonal bracing plates consists of at least two pieces, which are arranged at intervals along the length of the base plate and are vertically connected between the base plate and the adjacent side plate. This design enhances the overall rigidity and structural strength of the rear end, and can evenly transfer impact loads to both side plates. It also effectively suppresses the deformation of the side plates under stress, ensures the stability of the connection area with the support frame assembly, and improves structural reliability.

[0015] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application forms a structurally stable overall frame by combining the lower protective assembly 1, the support frame assembly 2 and the front protective assembly 3, which can effectively block the impact of gravel from the bottom, sides and front, reducing the risk of damage to the motor hydraulic radiator and its pipelines. The open layout on both sides and the rear takes into account the heat dissipation requirements, and the support frame assembly 2 and the frame are reliably installed. 2. By opening multiple elongated holes on the front baffle, this application not only ensures the front protection effect and structural strength, but also provides an air intake channel for the rear motor liquid radiator, thereby improving the heat dissipation efficiency. In addition, the opening holes reduce the overall structural weight and improve the lightweight effect. Attached Figure Description

[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] First, it should be noted that some directional terms used in the following description to clearly illustrate the technical solution of this utility model, such as the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," are all derived from the normal orientation of the components in the motor liquid buffer radiator protection structure. They are only used to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[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 2As shown in the figure, this application discloses a protective structure for a motor hydraulic radiator, which is installed between the vehicle frame and the front bumper. It can effectively block the impact and collision of foreign objects such as gravel on the mining road surface and prevent damage to the radiator body and pipes. The specific structure includes: a lower protective assembly 1, two support frame assemblies 2 and a front protective assembly 3. The lower protective assembly 1 is located below the motor hydraulic radiator, the two support frame assemblies 2 are respectively located on both sides of the rear end of the lower protective assembly 1, and the front protective assembly 3 is located at the front end of the lower protective assembly 1, thereby protecting the motor hydraulic radiator and its pipes.

[0023] The lower protective assembly 1 is responsible for bottom and side protection, including: The base plate 11 is arranged horizontally to block flying stones and obstacles from the ground; Two side plates 12 are respectively located on both sides of the base plate 11 and extend upward perpendicularly to the base plate 11 to block gravel flying in from the side. The top center of the side plate 12 is provided with a clearance notch 1201 to provide installation space for the front axle and avoid structural interference.

[0024] Support frame assembly 2 is used to connect with the vehicle frame and includes: L-shaped plate 21 has a vertical section 211 and a horizontal section 212. The lower part of the vertical section 211 is attached to and fixedly connected to the rear end of the corresponding side plate 12 to transmit the lateral and vertical impact forces received by the protective structure. The horizontal section 212 is located at the top of the vertical section 211 and extends horizontally outward. It may have multiple connection holes, so that it can be fixed to the bottom surface of the frame longitudinal beam by bolts, thereby realizing the final installation and fixing of the entire protective structure. Multiple reinforcing plates 22 are spaced between the vertical section 211 and the horizontal section 212 to enhance the structural rigidity and strength of this area, prevent the L-shaped plate 21 from bending or breaking when subjected to impact, and ensure that the load can be effectively and reliably transferred to the frame.

[0025] The front protective assembly 3 is responsible for blocking the frontal protection, including: The front baffle 31 is arranged vertically and extends along the width of the base plate 11 to block the impact of gravel or obstacles from the front of the vehicle. The inclined plate 32 has its top edge connected to the bottom edge of the front baffle 31, its bottom edge abutting against the front end of the base plate 11, and its two sides connected to the front ends of the two side plates 12 respectively. Through its inclined design, it effectively decomposes the horizontal impact force from the front into horizontal and vertical components, which are then transmitted to the base plate 11 below and the side plates 12 on both sides, greatly enhancing the overall stability and impact resistance of the structure.

[0026] This utility model forms a stable overall frame by combining the lower protective assembly 1, the support frame assembly 2 and the front protective assembly 3. It can effectively block the impact of gravel from the bottom, sides and front, and reduce the risk of damage to the motor hydraulic radiator and its pipeline. The open layout on both sides and the rear takes into account the heat dissipation requirements, and the support frame assembly 2 and the vehicle frame are reliably installed.

[0027] In some embodiments, such as Figure 1 and Figure 2 As shown, the front baffle 31 has multiple vertically arranged elongated holes 3101, and the elongated holes 3101 are arranged horizontally at intervals.

[0028] The above design ensures frontal protection and structural strength while providing an air intake channel for the rear motor liquid radiator, thereby improving heat dissipation efficiency. The openings also reduce the overall structural weight, enhancing the lightweight effect.

[0029] In some embodiments, such as Figure 3 As shown, the front protective assembly 3 includes: Two connecting components 33 are respectively located on the upper sides of the inner side of the front baffle 31 for detachable connection with the front bumper.

[0030] It should be noted that the two connecting components 33 are respectively located on both sides of the front baffle 31, which can distribute the impact load of the front baffle 31 to both ends of the front bumper, avoid stress concentration caused by single-point connection, ensure the reliability of the front protection assembly 3 installation, and ensure the continuous stability of the connection.

[0031] It should be noted that the connecting component 33 is located on the inner side of the front baffle 31, which allows fasteners such as bolts and the body of the connecting component 33 to be hidden behind the front baffle 31, effectively preventing them from being damaged by direct impact. It also keeps the outer surface of the front baffle 31 flat, avoiding the risk of it getting caught on obstacles, and improving the adaptability and reliability of the structure.

[0032] The above design achieves a rigid connection between the protective structure and the front bumper, effectively enhancing the overall structural strength and stability, preventing vibration or displacement due to road impacts, and the detachable connection facilitates the disassembly and maintenance of the protective structure, improving maintenance portability.

[0033] Based on the above embodiments, such as Figure 2 As shown, the connection component 33 includes: The mounting tube 331 is horizontally positioned on the inner side of the front baffle 31 to provide a mounting base, and has a large contact area to ensure connection strength. The threaded tube 332 is fixedly sleeved inside the outer end of the mounting tube 331. Its internal thread is used to cooperate with the connecting bolt, thereby realizing the fast connection between the front protection assembly 3 and the front bumper.

[0034] During installation, simply pass the bolt through the corresponding mounting hole on the front bumper and screw it directly into the threaded tube 332 to complete the fastening. This achieves blind installation and simplifies the installation and disassembly process.

[0035] The above design avoids stress concentration, ensures connection stability, and provides a precise, reliable, and wear-resistant threaded connection interface, improving the reliability and durability of the connection with the front bumper.

[0036] In some embodiments, such as Figure 3 As shown, the base plate 11 is divided into an installation area 111, a transition area 112 and a connection area 113 along its length from front to back. The width of the installation area 111 is greater than the width of the connection area 113, and the width of the transition area 112 gradually decreases from front to back.

[0037] It should be noted that the large front mounting area 111 can completely cover the projected area of ​​the motor liquid radiator, providing sufficient bottom protection; the middle transition area 112 can smoothly guide the load to the rear, avoiding stress concentration caused by abrupt changes in cross-section; the narrower rear connection area 113 is adapted to the routing and size of the pipeline, providing necessary protection while reducing the use of ineffective materials and improving structural compactness.

[0038] Through the above design, the structural shape of the base plate 11 is matched with the actual layout of the radiator and the pipeline, which not only provides comprehensive bottom protection for the radiator, but also achieves targeted protection for the pipeline, and completes the material simplification. While ensuring all-round protection, it also takes into account lightweight and structural compactness.

[0039] In some embodiments, such as Figure 2 As shown, the lower protective assembly 1 also includes: Two connecting plates 13 are respectively vertically disposed on the front end of the inner side of the two side plates 12, and the bottom edge of the connecting plate 13 is connected to the front end of the base plate 11; wherein, the two sides of the inclined plate 32 are respectively attached to the two connecting plates 13 and are detachably connected, which can be completed by fasteners such as bolts.

[0040] When the radiator needs to be inspected, there is no need to disassemble the entire protective structure. Simply remove the inclined plate 32 from the connecting plate 13 and the front baffle 31 from the front bumper to remove the front protective assembly 3 separately. This allows the front of the radiator to be fully exposed, thereby significantly reducing maintenance difficulty and operation time.

[0041] Through the above design, the impact force on the inclined plate 32 can be effectively dispersed and transmitted to the side plate 12 and the bottom plate 11, and a connection surface is provided for the inclined plate 32. The contact area is large and the connection is stable, ensuring the stress on fasteners such as bolts.

[0042] In some embodiments, such as Figure 2 As shown, a loading and unloading port 1101 is provided on the base plate 11.

[0043] The above design facilitates the installation and removal of the radiator drain valve by maintenance personnel, simplifies the maintenance process, improves work efficiency, and facilitates the full drainage of water accumulated on the base plate 11.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the lower protective assembly 1 also includes: Two sets of diagonal bracing plates 14 are respectively vertically installed on the rear sides of the top surface of the base plate 11. Each set of diagonal bracing plates 14 consists of at least two pieces, which are arranged at intervals along the length of the base plate 11 and are vertically connected between the base plate 11 and the adjacent side plate 12.

[0045] The above design enhances the overall rigidity and structural strength of the rear end, and can evenly transfer the impact load of the base plate 11 to the two side plates 12. It also effectively suppresses the outward tilting deformation of the side plates 12 under stress, ensures the stability of the connection area with the support frame assembly 2, and improves the structural reliability.
