Detailed Implementation
[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0014] See Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, this application proposes a plastic bracket for a truck air filter, comprising: a first plastic connecting plate 1; bracket fixing holes 12, the first plastic connecting plate 1 being provided with bracket fixing holes 12 at intervals to connect a vehicle frame 4; a plastic connecting arm 2, the plastic connecting arm 2 being connected to the first plastic connecting plate 1; a second plastic connecting plate 3, the second plastic connecting plate 3 being connected to the plastic connecting arm 2; and air filter assembly fixing holes 31, the second plastic connecting plate 3 being provided with air filter assembly fixing holes 31 at intervals to connect an air filter assembly 5.
[0015] The first plastic connecting plate 1 is a connecting end of a truck air filter plastic bracket, which is used to connect the frame 4. The frame 4 has a first connecting hole that matches the bracket fixing hole 12. The bolt passes through the bracket fixing hole 12 and the first connecting hole, and a lock nut is screwed on the part of the bolt that extends out of the first connecting hole. The connection between the first plastic connecting plate 1 and the frame 4 is achieved through standard fasteners, bracket fixing hole 12 and the first connecting hole, which helps to enhance the versatility of a truck air filter plastic bracket.
[0016] The plastic connecting arm 2 is integrally formed with the first plastic connecting plate 1 and the second plastic connecting plate 3. The plastic connecting arm 2 primarily serves a connecting function, connecting the second plastic connecting plate 3 and the air filter assembly 5 on the second plastic connecting plate 3 to the vehicle frame 4. Secondly, the plastic connecting arm 2 ensures sufficient clearance between the first plastic connecting plate 1 and the second plastic connecting plate 3, preventing interference between the air filter assembly 5 and other mounting structures on the vehicle frame 4.
[0017] The second plastic connecting plate 3 is another connecting end of a truck air filter plastic bracket. It is used to connect the air filter assembly 5. The air filter assembly 5 is provided with a second connecting hole that matches the air filter assembly mounting hole 31. A screw is screwed through the air filter assembly mounting hole 31 and into the second connecting hole, thereby forming a connection between the air filter assembly 5 and the second plastic connecting plate 3. The connection between the second plastic connecting plate 3 and the air filter assembly 5 is achieved through the air filter assembly mounting hole 31, the second connecting hole, and standard fasteners, which helps to enhance the versatility of a truck air filter plastic bracket.
[0018] Specifically, the first plastic connecting plate 1 is connected to the vehicle frame 4 via the bracket fixing holes 12 on the first plastic connecting plate 1 and fasteners. The air filter assembly 5 is fixed to the second plastic connecting plate 3 via the air filter assembly fixing holes 31 on the second plastic connecting plate 3 and fasteners, thereby connecting the air filter assembly 5 to the vehicle frame 4. This application provides a truck air filter plastic bracket that is firmly fixed, occupies little space, is highly versatile, low in cost, and saves time and effort in installation. Furthermore, the truck air filter plastic bracket is easy to standardize and serialize to meet the application needs of different vehicle models and reduce the development cost of air filter brackets.
[0019] One type of truck air filter plastic bracket is made of PA6+GF50 material. PA6+GF50 is a glass fiber reinforced nylon 6 (PA6) composite material, where "PA6" represents nylon 6, and "GF50" indicates that 50% glass fiber has been added to the material. PA6+GF50 material has high strength, good heat resistance, high toughness, and excellent corrosion resistance, which is conducive to the long-term stable fixation of the air filter assembly 5 to the frame 4.
[0020] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, it further includes: a first connecting surface 11, the surface of the first plastic connecting plate 1 facing the frame 4 is the first connecting surface 11; a first hollow structure 13, the first connecting surface 11 is provided with a first hollow structure 13, and the first hollow structures 13 on the first plastic connecting plate 1 are all blind grooves formed on the first connecting surface 11. It also includes: a second connecting surface 32, the surface of the second plastic connecting plate 3 facing the air filter assembly 5 is the second connecting surface 32; a second hollow structure 33, the second connecting surface 32 is provided with a second hollow structure 33, and the second hollow structures 33 on the second plastic connecting plate 3 are all blind grooves formed on the second connecting surface 32. It also includes: a bottom surface 21, the bottom surface 21 is provided at the bottom end of the plastic connecting arm 2; a third hollow structure 22, the bottom surface 21 is provided with a third hollow structure 22. The third hollow structures 22 on the plastic connecting arm 2 are all blind grooves formed on the bottom surface 21. The design of the first hollow structure 13, the second hollow structure 33 and the third hollow structure 22 mentioned above is beneficial to reduce the weight of the truck air filter plastic bracket while maintaining the strength of the truck air filter plastic bracket.
[0021] In this embodiment, the CAE analysis results of the truck air filter plastic bracket are as follows: Figure 2 - Figure 6 As shown, the CAE analysis results of the truck air filter plastic bracket indicate that:
[0022] Table 1 According to Table 1 above, the maximum stress of the plastic bracket for the truck air filter under the set working conditions is 118.35 MPa, which is less than the allowable stress of 120 MPa (0.6 * 200 MPa), thus meeting the strength requirements.
[0023] The first connecting surface 11 includes two planes to accommodate the bending of the frame 4 at the connection point with the first plastic connecting plate 1, thereby improving the stability of the connection between the first plastic connecting plate 1 and the frame 4.
[0024] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
