Description

Technical Field

[0001] The utility model belongs to the technical field of diesel engine parts, and particularly relates to a cover supporting structure and an air guide cover thereof. Background Art

[0002] In the related art, the fan of the diesel engine is directly mounted on the shell of the air scoop and is fixed by bolts installed through mounting holes.

[0003] However, since the shell of the air guide cover is a thin-walled layer, the operator may install each screw with different tightness when tightening the bolts, which will cause the shell of the fan installation surface to deform to varying degrees. When the fan is disassembled for maintenance, the position of the mounting hole of the shell will be offset, and the fan cannot be aligned with the mounting hole when it is installed again. At the same time, after the installation is completed, the direction of the fan may also be deflected.

[0004] Therefore, it is urgent to design a cover support structure and its air guide cover to solve the technical problem that when installing a fan on the shell of the above-mentioned air guide cover, the shell is deformed during the process of tightening the bolts, and the correct position of the fan cannot be guaranteed during the next installation.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Research has found that since the shell of the air guide cover is a thin-walled layer, the operator may install each screw with different tightness when tightening the bolts, which will cause the shell of the fan installation surface to deform to varying degrees. When the fan is disassembled for maintenance, the position of the mounting hole of the shell is offset, and the fan cannot be aligned with the mounting hole when it is installed again. At the same time, after the installation is completed, the direction of the fan may also deflect.

[0038] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by this disclosure for the above problems below should be the contributions made by the inventors to this disclosure during the disclosure process.

[0039] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced to effectively illustrate the technical content.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0041] Based on the above research, Figure 3 The embodiment of the present disclosure provides a cover support structure, including: a plurality of support pads 1 and reinforcement ribs 2, one end of the reinforcement rib 2 is connected to the support pad 1, and the other end is connected to the air duct cover. The support pad 1 is used to install and support the fan, so the support pad 1 is evenly distributed along the circumference of the air duct cover to ensure that the fan can provide support and positioning in the circumference when it is installed. Preferably, the support pad 1 and the reinforcement rib 2 are evenly molded into one piece with the air duct cover to achieve the best support effect, and a support pad 1 is set on the inner side of a threaded hole on the air duct cover. At the same time, a plurality of assembly holes 11 are fixed on the support pad 1, and the assembly hole 11 passes through the pad setting, and the assembly hole 11 corresponds to the threaded hole. When installing the fan, the operator aligns the various mounting holes of the fan with the assembly hole 11 and the threaded hole respectively, and then fixes the fan to the support pad 1 with bolts. At this time, the bolt plays the role of thickening the thickness of the bolt hole of the air duct cover to reduce the probability of bending the corresponding position of the bolt hole when the bolt is tightened. Furthermore, the thickness of the support pad 1 is designed in advance based on the length of the bolt to be selected, so that the thickness of the support pad 1 plus the threaded hole corresponds to the length of the bolt, so that when the bolt is fully tightened, it just passes through the bolt hole, thereby greatly reducing the probability of squeezing the air guide cover.

[0042] Reference Figure 2 Furthermore, by setting the reinforcing rib 2, the support pad 1 can be connected to the side wall of the air guide cover to strengthen the positioning of the support pad 1, further reducing the probability of the support pad 1 being deformed by the bolt, and ensuring that the fan can still maintain each support pad 1 in the same horizontal plane after multiple disassembly and use, without affecting the subsequent installation of the fan.

[0043] Reference Figure 1 The embodiment of the present disclosure also provides an air guide cover, including the cover support structure shown above, the air guide cover also includes a cover 3, an air inlet hole 30 is opened in the center of the cover 3, and the support pad 1 is arranged around the air inlet hole 30 so that the position of the air inlet hole 30 corresponds to the fan, so that external air can enter the air guide cover under the action of the fan.

[0044] Reference Figure 2 The top and bottom of the air duct are respectively provided with a main air outlet 31 and a secondary air outlet 32. After passing through the fan, the external air is divided into two streams, leaving the air duct from the main air outlet 31 and the secondary air outlet 32 ​​respectively, and entering the diesel engine.

[0045] Reference Figure 2 To guide the air flow, a main air guide plate 33 and a secondary air guide plate 34 are provided between the primary air outlet 31 and the secondary air outlet 32. These main air guide plates 33 and secondary air guide plates 34 are located on either side of the air inlet 30. After the outside air passes through the fan, some of it flows along the main air guide plate 33 toward the primary air outlet 31, while the rest flows along the secondary air guide plate 34 toward the secondary air outlet 32.

[0046] Reference Figure 2 The distance between the main air guide plate 33 and the air inlet 30 gradually decreases as it approaches the main air outlet 31, so that the air flow rate is accelerated under the guidance of the main air guide plate 33, thereby achieving a better cooling effect on the diesel engine. On the other hand, the distance between the secondary air guide plate 34 and the air inlet 30 gradually decreases as it approaches the secondary air outlet 32, so that the air flow rate is accelerated under the guidance of the main air guide plate 33, thereby achieving a better cooling effect on the diesel engine.
