Description

Technical Field

[0001] This utility model relates to the technical field of air filter support devices, and in particular to an engine air filter bracket and air filter device. Background Technology

[0002] The articulated dump truck features a split chassis design, consisting of front and rear frames. The front frame, as the main load-bearing structure of the power traction unit, houses critical components such as the engine, transmission, cooling system, intake and exhaust systems, and fuel system. These systems are essential for the vehicle's normal operation and power output; none can be omitted. However, the efficient placement of these components within the limited space of the front frame results in an exceptionally compact spatial structure. Furthermore, articulated dump trucks undertake heavy material handling tasks in extremely harsh working environments, including soft sand, potholed dirt roads, muddy areas, and steep slopes.

[0003] In current engine intake systems, the air filter bracket serves to support and secure the air filter. However, traditional air filter brackets suffer from complex installation structures, requiring multiple tools and cumbersome operations. This not only increases the labor intensity and time costs for assembly workers but also makes disassembly extremely inconvenient during later maintenance and air filter replacement. Furthermore, under the vibrations and complex operating conditions generated by the engine, traditional air filter brackets are prone to loosening, deformation, or even damage, affecting the normal operation of the air filter, thereby reducing engine intake efficiency and leading to a decline in engine performance.

[0004] Therefore, it is particularly necessary to develop a new type of engine air filter bracket to solve the above problems. Utility Model Content

[0007] An engine air filter bracket includes a bracket body and a mounting base. The bracket body includes a first mounting plate and a second mounting plate. One end of the first mounting plate is fixedly connected to the second mounting plate to form an L-shaped bracket. The air filter is fixedly connected to the L-shaped bracket. The mounting base is disposed on the side of the first mounting plate away from the air filter. The mounting base has mounting holes. The first mounting plate is fixedly connected to the vehicle frame through the mounting base.

[0008] Furthermore, the main body of the bracket also includes a plurality of stiffening plate supports, which are spaced apart on the side of the second mounting plate away from the air filter.

[0009] Furthermore, the stiffener support extends along the second mounting plate toward the first mounting plate and is fixedly connected to the mounting base.

[0010] Furthermore, the engine air filter bracket also includes reinforcing ribs, which are fixedly connected to the rib support and the mounting base, respectively.

[0030] An embodiment of this application discloses an engine air filter bracket, including a bracket body 100 and a mounting base 200. The bracket body 100 includes a first mounting plate 110 and a second mounting plate 120. One end of the first mounting plate 110 is fixedly connected to the second mounting plate 120 to form an L-shaped bracket. An air filter 300 is fixedly connected to the L-shaped bracket. The mounting base 200 is disposed on the side of the first mounting plate 110 away from the air filter 300. The mounting base 200 is provided with a mounting hole 210. The first mounting plate 110 is fixedly connected to the vehicle frame through the mounting base 200.

[0031] like Figures 1 to 2 As shown, the engine air filter bracket disclosed in this application sets the bracket body 100 into an L-shaped bracket structure. Specifically, it sets a first mounting plate 110 and a second mounting plate 120. One end of the two mounting plates is connected by welding or other fixing methods to form an L-shaped structure, which provides a stable support platform for the engine air filter, so that the air filter can be firmly installed in the vehicle or mechanical equipment, while ensuring the maximization of space utilization.

[0032] Furthermore, by providing a mounting base 200 and mounting holes 210 on the side of the first mounting plate 110 away from the air filter, the entire bracket body 100 can be quickly and securely fixed to the vehicle frame or other predetermined positions using standard fasteners such as bolts. The design of the mounting base 200 and mounting holes 210 greatly simplifies the air filter bracket installation process, improves the installation efficiency of the bracket body 100, and facilitates subsequent maintenance and replacement operations.

[0033] In summary, by using the first mounting plate 110 and the second mounting plate 120 to form an L-shaped bracket, the first mounting plate 110 and the mounting base 200 provide support for the air filter 300 and the second mounting plate 120. Simultaneously, the second mounting plate 120 provides secure protection to the sides of the air filter 300. The first mounting plate 110 and the second mounting plate 120 form a semi-enclosed structure for the air filter 300. This semi-enclosed structure not only enhances the structural strength of the air filter bracket and effectively prevents the air filter 300 from loosening or being damaged due to road bumps or mechanical vibrations, but also facilitates the installation and removal of the air filter 300. Furthermore, the semi-open air filter bracket allows users to perform routine inspections, maintenance, and replacement operations, reducing maintenance costs and time. In addition, the L-shaped bracket design makes the installation position of the air filter 300 more reasonable, avoiding interference between the air filter bracket and other components, and ensuring the normal operation of the air filter 300 and the engine.

[0034] In one embodiment of this application, the bracket body 100 further includes a plurality of rib support members 130, which are spaced apart on the side of the second mounting plate 120 away from the air filter 300.

[0035] like Figures 1 to 3 As shown, the main body 100 of the support frame not only includes the L-shaped support structure formed by the first mounting plate 110 and the second mounting plate 120, but also further includes multiple stiffening support members 130. These stiffening support members 130 are spaced apart on the side of the second mounting plate 120 away from the air filter 300, working together with the L-shaped support frame to provide stronger support and stability. Specifically, each stiffening support member 130 is vertically fixed to the second mounting plate 120, and its stability is ensured by welding or other robust connection methods. The stiffening support members 130 can be evenly spaced, or the spacing can be adjusted according to actual needs to achieve the best support effect. By adding multiple stiffening support members 130, the structural strength and stability of the entire air filter support frame are significantly improved, the vibration resistance of the frame is greatly enhanced, the continuous vibration generated by the air filter 300 during operation is effectively resisted, the risk of component damage caused by vibration is reduced, and the service life of the air filter support frame is extended.

[0036] To further enhance the strength of the stiffener support 130 and its connection with the second mounting plate 120, reinforcing ribs are provided at the connection between the stiffener support 130 and the second mounting plate 120. The reinforcing ribs are fixedly connected to the stiffener support 130 and the second mounting plate 120 respectively. By providing reinforcing ribs, the rigidity and vibration resistance of the entire structure can be improved, and fatigue damage caused by long-term vibration can be prevented.

[0037] In one embodiment of this application, the stiffener support 130 extends along the second mounting plate 120 toward the first mounting plate 110 and is fixedly connected to the mounting base 200.

[0038] like Figures 1 to 3 As shown, in a preferred embodiment of this application, the stiffening support members 130 are not only spaced apart on the side of the second mounting plate 120 away from the air filter 300, but also extend along the second mounting plate 120 toward the first mounting plate 110, and are ultimately fixedly connected to the mounting base 200. Specifically, the stiffening support members 130 start from the second mounting plate 120 and extend toward the first mounting plate 110, extending to a position where they connect with the mounting base 200, and are fixed to the mounting base 200 by welding, bolts, or other robust connection methods. This design significantly improves the overall rigidity and stability of the entire air filter bracket. This structural design can more effectively withstand forces from all directions, ensuring the air filter remains stable. It also enhances its resistance to external impacts. In addition, this design can disperse the vibration generated by the air filter 300 during operation across the entire bracket, reducing local stress concentration.

[0039] In one embodiment of this application, the engine air filter bracket further includes a reinforcing rib plate 400, which is fixedly connected to the rib plate support member 130 and the mounting base 200 respectively.

[0040] like Figures 1 to 3 As shown, in one embodiment of this application, the engine air filter bracket further incorporates a reinforcing rib 400 design. The reinforcing rib 400 can be firmly connected to the rib support 130 and the mounting base 200 by welding, bolting, or other high-strength connection technologies. The reinforcing rib 400 has sufficient rigidity and strength to withstand the gravity between the bracket body 100 and the air filter 300, enhancing the integrity of the entire bracket structure, significantly improving the structural strength and stability of the entire air filter bracket, and also improving its resistance to vibration and impact.

[0041] In addition, the presence of the reinforcing rib 400 helps to better absorb and disperse the vibration energy generated during engine operation, thereby reducing the probability of local stress concentration. This not only protects the air filter from damage but also extends the service life of the bracket itself.

[0042] In one embodiment of this application, the stiffener support 130 and the mounting base 200 are integrally formed.

[0043] In a preferred embodiment of this application, the stiffener support 130 and the mounting base 200 are integrally molded. By designing the stiffener support 130 and the mounting base 200 as an integrally molded structure, a seamless connection between the stiffener support 130 and the mounting base 200 can be achieved. This method not only simplifies the manufacturing process but also ensures the connection strength and consistency between the two components. Since the stiffener support 130 and the mounting base 200 are integrally molded, there are no potential weak points caused by connection points, and the structural strength of the entire air filter bracket is significantly improved.

[0044] In addition, compared with traditional assembly methods, one-piece molding reduces the risk of failure caused by poor welding or loose bolts, and improves the long-term stability and reliability of the system, especially in the face of severe vibration and impact.

[0045] Meanwhile, by designing it as a one-piece molded structure, the assembly steps between the stiffener support 130 and the mounting base 200 are reduced, thereby shortening the production cycle and reducing manufacturing costs. Furthermore, it reduces quality problems caused by assembly errors and more effectively absorbs and disperses vibration energy generated during engine operation, further improving vibration resistance and helping to protect the air filter from damage.

[0046] In one embodiment of this application, the first mounting plate 110 is provided with a plurality of first fixing holes 111, the second mounting plate 120 is provided with a plurality of second fixing holes 121, and the air filter 300 is fixedly connected to the first fixing holes 111 and the second fixing holes 121 by bolts.

[0047] like Figures 1 to 3 As shown, the first mounting plate 110 and the second mounting plate 120 are respectively provided with multiple first fixing holes 111 and second fixing holes 121. High-strength bolts are passed through the corresponding holes on the air filter 300 and the first fixing holes 111 and second fixing holes 121, and then locked with nuts or other fasteners. This method not only ensures the firmness of the connection, but also allows the position of the air filter 300 to be adjusted as needed to achieve the best installation effect. When it is necessary to replace or clean the air filter, the air filter 300 can be quickly disassembled simply by loosening the corresponding bolts, simplifying the maintenance process and saving time and labor costs. At the same time, it also facilitates subsequent inspection and maintenance work.

[0048] In one embodiment of this application, the first mounting plate 110 and the second mounting plate 120 are connected by an arc-shaped transition structure.

[0049] like Figure 2As shown, the arc-shaped transition design at the connection between the first mounting plate 110 and the second mounting plate 120 significantly enhances the connection strength. Compared to traditional right-angle or acute-angle connections, the arc-shaped design distributes stress more evenly, reducing the possibility of localized stress concentration and the risk of cracks or fractures caused by stress concentration, thereby improving the overall structural strength of the bracket. Furthermore, the arc-shaped transition structure helps absorb and disperse the vibration energy generated during engine operation, reducing the risk of fatigue damage due to long-term vibration. Especially in high-vibration environments, this design better protects the air filter and its internal components, extending the equipment's service life.

[0050] In one embodiment of this application, the first mounting plate 110 and / or the second mounting plate 120 are provided with a cutout window 500.

[0051] like Figures 1 to 3 As shown, by providing perforated windows 500 on the first mounting plate 110 and / or the second mounting plate 120, the weight of the entire air filter bracket is effectively reduced. This not only helps improve the operational flexibility of the equipment but also reduces unnecessary loads, which has a positive effect on improving fuel economy and reducing energy consumption. Specifically, by placing the perforated windows 500 in areas that do not affect the overall structural strength, such as parts with relatively uniform stress distribution, and by accurately calculating and simulating to determine the optimal position and size, it is ensured that weight can be reduced without weakening the load-bearing capacity of the bracket. In addition, the presence of perforated windows 500 increases the space for air circulation, which is beneficial to enhancing the ventilation conditions of the air filter 300.

[0052] It should be noted that this application does not limit the shape of the cutout window 500. In one embodiment, the cutout window 500 can be a regular shape (such as a rectangle, circle or polygon).

[0053] In one embodiment of this application, the first mounting plate 110 and the second mounting plate 120 are integrally formed. By adopting an integrally formed structure for the first mounting plate 110 and the second mounting plate 120, there are no potential weak points caused by welding points or bolt connections between them. This greatly enhances the structural strength and stability of the entire air filter bracket, making it more able to withstand forces from all directions and ensuring the stable installation of the air filter. At the same time, the integrally formed structure reduces problems caused by improper connection methods (such as poor welding or loose bolts), improving the long-term stability and reliability of the system. In addition, the integrally formed structure eliminates gaps or weakened areas in traditional connection methods, which can better absorb and disperse the vibration energy generated during engine operation, further improving vibration resistance.

[0054] This utility model also provides an air filter device, which includes the aforementioned engine air filter bracket.

[0055] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
