AI Technical Summary
The fixing method of existing engine exhaust after-treatment systems will increase the engine weight, affect stability and shock absorption, or lead to insufficient weld strength.
A bending integrated support frame structure is adopted, including the first steel pipe, the second steel pipe and the cross beam, connected by arc-shaped junction to avoid defects in the welded structure and fixed on the frame so as not to increase the engine weight.
The fixing method is realized without increasing the engine weight, which enhances the reliability of the fixing of the engine installation and avoids the problem of insufficient weld strength.

[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
[0017] like Figure 1 As shown, the utility model provides a support frame structure for supporting an engine aftertreatment system and an air filter, comprising a first steel pipe 100, a crossbeam 200 connected to the first steel pipe 100 at one end, and a second steel pipe 300 connected to one end of the crossbeam 200, forming a support structure.
[0018] The first steel pipe 100 includes a first fixing portion 110 and a first supporting portion 120 integrally connected to one end of the first fixing portion 110, and the other end of the first supporting portion 120 is connected to the crossbeam 200. The first fixing portion 110 and the first supporting portion 120 are both hollow steel pipes. Preferably, the intersection of the first fixing portion 110 and the first supporting portion 120 is arc-shaped.
[0019] The second steel pipe 300 includes a second fixing portion 310 and a second supporting portion 320 integrally connected to one end of the second fixing portion 310, and the other end of the second supporting portion 320 is connected to the crossbeam 200. The second fixing portion 310 and the second supporting portion 320 are both hollow steel pipes. Preferably, the intersection of the second fixing portion 310 and the second supporting portion 320 is arc-shaped.
[0020] In this embodiment, the second support portion 320 is arranged parallel to the first support portion 120, and the length of the second support portion 320 is shorter than that of the first support portion 120; the length of the second fixing portion 310 is consistent with the length of the first fixing portion 110, ensuring that the bottom surfaces of the first fixing portion 110 and the second fixing portion 310 are in the same plane, ensuring the stability of the fixation to the frame.
[0021] In this embodiment, a fixing steel plate 400 is installed on the bottom surfaces of the first fixing portion 110 and the second fixing portion 310 , which can increase the contact area between the first fixing portion 110 and the second fixing portion 310 and the vehicle frame and improve the stability of the supporting structure.
[0022] In order to further improve the stability of the support frame structure, a positioning hole (not marked in the figure) is opened on the fixed steel plate 400. When the support frame structure needs to be fixed on the frame, fixing components such as bolts or screws are used to pass through the positioning hole and then fixedly connected to the frame to achieve fixation of the two.
[0023] In order to improve the supporting performance of the support frame structure and increase the supporting area, a supporting steel plate 500 is fixedly installed on the upper surface of the first support part 120 and the second support part 320. The area of the supporting surface of the first support part 120 and the second support part 320 is increased, so that the engine aftertreatment system and the air filter placed thereon are more stable. Preferably, the supporting steel plate 500 is welded and fixed to the contact surface of the corresponding first support part 120 and the second support part 320, and one end of the supporting steel plate 500 is welded and fixed to the crossbeam 200. The supporting steel plate 500 can not only increase the supporting area of the first support part 120 and the second support part 320, but also improve the connection stability between the first support part 120 and the second support part 320 and the crossbeam 200.
