Technical Field
[0001] The utility model relates to a structure related to a motor vehicle engine, in particular to an air intake structure of a motor vehicle engine and a motor vehicle having the air intake structure. Background Art
[0002] A motor vehicle needs to use an engine when operating, and the engine needs to input external gas into it during operation. Especially for some large special motor vehicles, their fuel consumption is huge, so more gas is required. The air intake cylinder will be designed larger, and in order to meet the requirements of the actual working environment, it will be designed as a telescopic cylinder. After the air intake cylinder is designed larger and as a telescopic cylinder, it is easy for external rainwater, etc. to enter the air intake cylinder, which may cause the engine to stall or even malfunction. Content of the Utility Model
[0003] Therefore, it is necessary for the utility model to provide an air intake structure of a motor vehicle engine and a motor vehicle having the air intake structure to reduce the risk of the engine stalling or even malfunction due to water ingress.
[0004] The utility model provides an air intake structure of a motor vehicle engine. The engine air intake structure includes a telescopic inner cylinder, a corrugated pipe, a first mounting plate, a second mounting plate and two connecting structures. An air inlet is provided near the top of the top cylinder of the telescopic inner cylinder, and a water baffle is provided above the air inlet on the top cylinder. The corrugated pipe is sleeved outside the telescopic inner cylinder. The first mounting plate is fixed to the top cylinder and is located below the air inlet. The second mounting plate is arranged on the motor vehicle. The corrugated pipe includes a pipe portion and connecting pieces at both ends. One connecting structure connects the connecting piece at one end to the first mounting plate, and the other connecting structure connects the connecting piece at the other end to the second mounting plate. The connecting structure includes a compression ring, a sealing ring and a rubber tongue piece. The compression ring is used to press the connecting piece against the first mounting plate or the second mounting plate and to press the sealing ring between the first mounting plate and the connecting piece or between the second mounting plate and the connecting piece. The rubber tongue piece is installed inside the compression ring, and the rubber tongue piece abuts against the pipe portion.
[0005] Further, the second mounting plate protrudes from the upper outer surface of the motor vehicle.
[0006] Further, the compression ring is connected to the first mounting plate or the second mounting plate by bolts to press the connecting piece against the first mounting plate or the second mounting plate.
[0007] The utility model also provides a motor vehicle, which includes a vehicle body having an upper outer surface, and the motor vehicle also includes the above-mentioned air intake structure of the motor vehicle engine.
[0008] Advantages of the present utility model: In the present utility model, the air inlet is arranged at a position near the top of the top cylinder of the telescopic inner cylinder, and a water baffle is provided above the air inlet on the top cylinder. The water baffle can prevent rainwater from entering the telescopic inner cylinder. The corrugated pipe is sleeved outside the telescopic inner cylinder, and both ends are hermetically connected to the corresponding first mounting plate or the second mounting plate through a connecting structure, so that rainwater cannot penetrate into its interior from the gap between the telescopic inner cylinders. Moreover, since the ends of the corrugated pipe are fixed, stress will be pulled at the ends during the telescopic process of the corrugated pipe and it will be squeezed by the pressure ring, resulting in the ends of the corrugated pipe being easily torn. In the present utility model, a rubber tongue is arranged inside the pressure ring, and the rubber tongue abuts against the pipe part of the corrugated pipe. Therefore, during the telescopic process of the corrugated pipe, the end of the pipe part will elastically contact the rubber tongue, thereby releasing stress and extrusion force through the rubber tongue, which can reduce the possibility of the ends of the corrugated pipe being torn, thus preventing rainwater from entering the inside of the corrugated pipe from this place and then penetrating into the interior of the telescopic inner cylinder. Therefore, the present utility model can reduce the risk of the engine stalling or even malfunctioning due to water ingress. Description of the Drawings
[0009] Figure 1 It is a schematic structural diagram of the intake structure of a motor vehicle engine in a specific embodiment.
[0010] Figure 2 is Figure 1 a sectional view taken at A of Detailed Embodiments
[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0012] As Figure 1 and Figure 2 shown, this embodiment provides an intake structure 100 for a motor vehicle engine. The engine intake structure 100 includes a telescopic inner cylinder 10, a corrugated pipe 20, a first mounting plate 30, a second mounting plate 40, and two connecting structures 50.
[0013] Among them, an air inlet 111 is provided near the top of the top cylinder 11 of the telescopic inner cylinder 10, and a water baffle 112 is provided above the air inlet 111 on the top cylinder 11.
[0014] The corrugated pipe 20 is sleeved outside the telescopic inner cylinder 10. The first mounting plate 30 is fixed to the top cylinder 11 and is located below the air inlet 111. The second mounting plate 40 is arranged on the motor vehicle. The corrugated pipe 20 includes a pipe portion 21 and connecting pieces 22 at both ends. One connecting structure 50 connects the connecting piece 22 at one end to the first mounting plate 30, and the other connecting structure 50 connects the connecting piece 22 at the other end to the second mounting plate 40.
[0015] The two connecting structures 50 are the same. Specifically, taking the connecting structure 50 located below as an example, as Figure 2 shown, the connecting structure 50 includes a compression ring 51, a sealing ring 52 and a rubber tongue piece 53. The compression ring 51 is used to press the connecting piece 22 at the lower end of the corrugated pipe 20 against the second mounting plate 40, and to press the sealing ring 52 between the second mounting plate 40 and the connecting piece 22 below. The rubber tongue piece 53 is installed inside the compression ring 51, and the rubber tongue piece 53 abuts against the pipe portion 21.
[0016] It can be understood that the connecting structure 50 located above presses the connecting piece 22 at the upper end of the corrugated pipe 20 against the first mounting plate 30, and presses the sealing ring 52 between the first mounting plate 30 and the connecting piece 22 above.
[0017] The beneficial effects of the present utility model are as follows: The present utility model sets the air inlet 111 at a position close to the top of the top cylinder 11 of the telescopic inner cylinder 10, and a water baffle 112 is provided above the air inlet 111 on the top cylinder 11. The water baffle 112 can prevent rainwater from entering the telescopic inner cylinder 10. The corrugated pipe 20 is sleeved outside the telescopic inner cylinder 10, and both ends are hermetically connected to the corresponding first mounting plate 30 or the second mounting plate 40 through the connecting structure 50, so that rainwater cannot penetrate into its interior from the gap between the telescopic inner cylinders 10. Moreover, since the end of the corrugated pipe 20 is fixed, stress pulling will be formed at the end during the telescopic process of the corrugated pipe 20 and it will be squeezed by the compression ring 51, resulting in the end of the corrugated pipe 20 being easily torn. The present utility model provides a rubber tongue piece 53 inside the compression ring 51, and the rubber tongue piece 53 abuts against the pipe portion 21 of the corrugated pipe 20. Therefore, during the telescopic process of the corrugated pipe 20, the end of the pipe portion 21 will elastically contact the rubber tongue piece 53, thereby releasing stress and extrusion force through the rubber tongue piece 53, which can reduce the possibility of the end of the corrugated pipe 20 being torn, thus preventing rainwater from entering the inside of the corrugated pipe 20 from this place and then penetrating into the inside of the telescopic inner cylinder 10. Therefore, the present utility model can reduce the risk of the engine stalling or even malfunction due to water ingress.
[0018] More specifically, the second mounting plate 40 protrudes from the upper outer surface 200 of the motor vehicle to prevent water accumulation on the second mounting plate 40.
[0019] The pressure ring 51 is bolted to the first mounting plate 30 or the second mounting plate 40 to press the connecting piece 22 against the first mounting plate 30 or the second mounting plate 40.
[0020] The present utility model further provides a motor vehicle, which includes a vehicle body having an upper outer surface 200, and the motor vehicle further includes the motor vehicle engine intake structure 100 as described above.
[0021] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
