Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and in particular to a water wading throat structure of a high-position air intake pipe of a vehicle. The present invention also relates to a high-position air intake structure of a vehicle having the water wading throat structure, and a control method of the air intake structure. Background Art

[0002] With the development of the automobile industry and the continuous improvement of people's living standards, cars no longer appear in people's daily lives just as a means of transportation. Driving off-road vehicles for off-roading and playing in the sand is gradually becoming popular and is being sought after by more and more outdoor car enthusiasts.

[0003] In order to increase the wading depth of off-road vehicles, the use of high-position air intake pipes has become an essential structure for off-road vehicles to improve their off-road performance. At present, in order to ensure the air intake efficiency, the air intake direction of the wading throat of the high-position air intake pipes of off-road vehicles on the market is generally consistent with the forward driving direction of the vehicle, so that the airflow during driving can be fully utilized to obtain a better air intake effect.

[0004] However, with the existing wading hose air intake method, in rainy and snowy weather, rain and snow in the air are easily sucked into the high-position intake pipe and brought into the air filter, thereby damaging the performance of the air filter. In severe cases, water may even enter the engine, creating a safety hazard. Summary of the invention

[0005] In view of this, the present invention aims to provide a wading throat structure for a high-position air intake pipe of a vehicle, so as to prevent rainwater from entering the high-position air intake pipe in rainy and snowy weather and causing damage to the air filter and even the engine.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A wading throat structure of a high-position air intake pipe of a vehicle is located at the top of the high-position air intake pipe partially extending along the A-pillar of the vehicle, and the wading throat structure comprises:

[0008] A wading hose body, wherein the wading hose body is at least configured with a first air inlet arranged toward the front of the vehicle and a second air inlet arranged toward the bottom;

[0009] An air inlet switching mechanism is disposed on the snorkel body. The air inlet switching mechanism includes a baffle and a driving unit that is transmission-connected to the baffle. In response to an external control signal, the driving unit can drive the baffle to switch between the first air inlet and the second air inlet positions.

[0010] Furthermore, the first air inlet is arranged adjacent to the second air inlet, the baffle is provided between the first air inlet and the second air inlet, and is switched between the positions of the first air inlet and the second air inlet by pivoting the baffle driven by the driving unit.

[0011] Furthermore, the baffle is pivotally disposed on the wading hose body and is configured to pivot within the wading hose body.

[0012] Furthermore, the driving part includes a rotational power output device fixedly connected to the wading hose body, and a reduction transmission structure connected between the power output end of the rotational power output device and the baffle.

[0013] Furthermore, the rotary power output device adopts an electric motor.

[0014] Furthermore, the reduction transmission structure adopts a worm gear reduction mechanism or a gear reduction mechanism.

[0015] Furthermore, directly opposite to the first air inlet, a dust exhaust port is provided on the wading hose body and is arranged toward the rear of the vehicle.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The wading pipe structure of the vehicle high-position air intake pipe of the present invention can select to open the second air intake port facing downward when driving in rainy and snowy weather, and select to open the first air intake port facing forward when driving in rainy and snowy weather, by setting two air intake ports facing forward and downward, and by setting an air intake port switching mechanism. In this way, rainwater in rainy and snowy weather can be prevented from entering the high-position air intake pipe through the wading pipe, thereby damaging the air filter and even the engine, and the first air intake port can be used to fully utilize the airflow during driving when there is no rain or snow, so as to obtain a better air intake effect.

[0018] Another object of the present invention is to provide a high-position air intake structure for a vehicle, comprising a high-position air intake pipe partially extending along the A-pillar of the vehicle, the top of the high-position air intake pipe having a wading throat structure of the high-position air intake pipe of the vehicle as described above, and the high-position air intake structure of the vehicle further comprising:

[0019] A control unit, located on the vehicle and connected to the driving unit;

[0020] The triggering unit is located on the vehicle and connected to the control unit. The triggering unit can be triggered by the outside world. The control unit can output an external control signal in response to the triggering signal of the triggering unit.

[0021] Furthermore, the control unit is integrated into a body controller of the vehicle, and the trigger unit includes at least one of a touch switch and a rain and snow sensing component connected to the body controller.

[0022] The high-position air intake structure of the present invention adopts the above-mentioned wading throat structure and is provided with a control unit and a trigger unit, so that the two air intake ports can be switched according to the external driving environment or the driver's wishes. In this way, when driving in rainy or snowy weather, the second downward air intake port can be selected to intake air, thereby preventing rainwater from entering the intake pipe and preventing damage to the air filter and even the engine.

[0023] In addition, the present invention also proposes a control method for a vehicle high-position air intake structure, wherein the vehicle high-position air intake structure has the above-mentioned wading throat structure of the vehicle high-position air intake pipe, and the control method comprises:

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0040] Embodiment 1

[0041] This embodiment firstly relates to a wading throat structure of a vehicle high-position air intake pipe, referring to Figure 1 and Figure 2 As shown in the figure, the wading throat structure is located at the top of the high-position air intake pipe that is partially extended along the A-pillar 3 of the vehicle, and the wading throat structure specifically includes a wading throat body 2 and an air intake switching mechanism arranged on the wading throat body 2.

[0042] Among them, in the wading throat structure located at the top of the high-position air intake pipe, the wading throat body 2 is specifically connected to the high-position air intake pipe body 1 in the high-position air intake pipe. The high-position air intake pipe body 1 is extended along the vehicle A-pillar 3, and the bottom of the high-position air intake pipe body 1 enters the engine compartment below the engine hood 4. In the engine compartment, the high-position air intake pipe body 1 is connected to the air filter 5, and the air filter 5 is connected to the air intake of the engine 6, thereby forming an overall engine air intake passage.

[0043] In this embodiment, the structure of the high-position air intake pipe body 1 and its installation and fixation on the vehicle body including the vehicle A-pillar 3 can be directly referred to the existing off-road vehicle structure using a high-position air intake method. As for the wading throat structure of this embodiment, the basic structure of the wading throat body 2 is also similar to the wading throat part of the high-position air intake pipe of an off-road vehicle generally used in the prior art, that is, the wading throat body 2 is a bent tubular structure.

[0044] However, unlike the wading hose in the prior art, as one of the inventive points of the wading hose structure of this embodiment, this embodiment is constructed with a first air inlet 201 arranged toward the front of the vehicle and a second air inlet 202 arranged toward the bottom on the wading hose body 2. At this time, the first air inlet 201 is arranged toward the front of the vehicle, that is, it faces the direction of the vehicle's forward travel, so it can naturally make full use of the airflow during driving and obtain a better air intake effect. The second air inlet 202 is arranged toward the bottom, which means that the air inlet opens downward, so that the outside air must first enter the second air inlet 202 from bottom to top, and then it can enter the high-position air intake pipe body 1 through the wading hose like the airflow entering the first air inlet 201.

[0045] It should be noted that the first air inlet 201 of this embodiment is arranged toward the front, which not only includes the case where the overall opening direction of the air inlet is horizontal, but also includes the case where the overall opening direction of the first air inlet 201 forms a certain degree of angle with the horizontal direction, which is also arranged toward the front of the vehicle. Of course, in order to obtain better air intake performance, the overall opening direction of the first air inlet 201 is generally designed to be horizontal as much as possible.

[0046] The downward arrangement of the second air inlet 202 has the same meaning as the first air inlet 201, that is, including the situation where the second air inlet is vertically oriented as a whole, and the situation where it has a certain degree of angle with the vertical direction. Of course, the vertical here refers to the situation where the vehicle is in a horizontal state as a whole.

[0047] In this embodiment, the air inlet switching mechanism specifically includes a baffle 7 and a driving unit 8 that is transmission-connected to the baffle 7, and in terms of design, the driving unit 8 can drive the baffle 7 to move in response to an external control signal, so as to switch between the positions of the first air inlet 201 and the second air inlet 202. Thus, the first air inlet 201 and the second air inlet 202 can be opened selectively, or the two air inlets can be opened simultaneously, and the air inlet cross-sections of the two air inlets can be adjusted at this time.

[0048] At this time, as a preferred embodiment, Figure 2 As shown, the first air inlet 201 and the second air inlet 202 of the present embodiment are arranged adjacent to each other, and the baffle 7 is arranged between the first air inlet 201 and the second air inlet 202. At the same time, the baffle 7 is driven to pivot by the driving unit 8 to realize the switching between the positions of the first air inlet 201 and the second air inlet 202.

[0049] Based on this preferred embodiment, further, the baffle 7 of this embodiment can generally be pivotally arranged on the wading hose body 2 via one end thereof, and the baffle 7 can also be arranged to pivot inside the wading hose body 2. With such a design, compared with the case where the baffle 7 is located outside the wading hose body 2, the baffle 7 located inside the wading hose body 2 can better protect the air inlet switching mechanism including the baffle 7, so as to ensure its stability and durability in use.

[0050] This embodiment matches the above rotation setting of the baffle 7, such as Figure 3 As shown in the figure, the driving part 8 comprises a rotary power output device 9 fixedly connected to the wading hose body 2, and a reduction transmission structure 10 connected between the power output end of the rotary power output device and the baffle 7. The rotary power output device 9 is generally a motor, and the reduction transmission structure 10 can be a worm gear reduction mechanism or a gear reduction mechanism, and the rotary power output device 9 and the reduction transmission structure 10 can be installed in a mounting housing 11 fixedly connected to the wading hose body 2.

[0051] In this embodiment, it should be noted that, in order to ensure that the baffle 7 can better close the first air inlet 201 and the second air inlet 202, generally, the two air inlets are designed so that their opening cross-sections can be slightly smaller than the cross-section of the baffle 7 used to block the air inlets, and in specific implementation, for example, a "mouth"-shaped shielding structure can be added at each air inlet position to reduce the cross-section of the air inlet. This makes the cross-section of the air inlet smaller than the cross-section of the baffle 7, which is particularly critical for the first air inlet 201, because such a setting can substantially limit the closing action of the baffle 7.

[0052] In this embodiment, after the baffle 7 is driven by the driving unit 8 to move to one of the air inlet positions, the position of the baffle 7 can be locked by, for example, the self-locking of the motor, or, for example, a self-locking structure that can cooperate with the baffle 7 can be provided at each air inlet, corresponding to the limit position of the baffle 7, that is, the position where the air inlet of the baffle 7 is closed. The self-locking structure can be, for example, a self-locking form of electromagnetic energization and self-locking form of a push-pull limit pin and a corresponding pin hole.

[0053] It should also be noted that in this embodiment, in addition to the above-mentioned baffle being only pivotally arranged, it is of course feasible to choose to set two baffles 7 to separately control each air inlet. In this case, the air inlet switching mechanism including two baffles 7 is equivalent to realizing opening and closing control through the on-off valve structure respectively arranged at the position of each air inlet.

[0054] In addition, in addition to using the baffle 7 that is arranged to rotate, of course, this embodiment chooses to set the baffle 7 to a sliding arrangement, which is also possible. However, when it is set to a sliding structure, the baffle 7 should generally use two baffles 7 that correspond to the two air inlets one by one, and at this time, the driving part that drives the baffle 7 to move in conjunction with the sliding baffle 7 can still use a rotary power output device such as a motor, and the rotary power output device is also connected to the baffle 7 through a reduction transmission structure, a gear rack and other reversing structures. Alternatively, when a sliding baffle 7 is used, the driving part directly uses a linear power output device such as a push-pull electromagnet, a linear motor, etc.

[0055] In addition, in this embodiment, in addition to the first air inlet 201 and the second air inlet 202 are provided on the wading hose body 2, Figure 4 As shown in FIG. 1 , as another embodiment, a dust discharge port 15 arranged toward the rear of the vehicle can be optionally provided on the wading hose body 2 in correspondence with the first air inlet 201. At this time, by providing the dust discharge port 15, solid particles can be effectively prevented from entering the high-position air intake pipe when the first air inlet 201 is used for air intake, thereby playing a role of coarse filtering.

[0056] The wading hose structure of this embodiment, through the driving unit 8 driving the baffle 7, uses the first air inlet 201 to take in air (that is, the second air inlet 202 is closed) as shown in the following state: Figure 5 As shown in FIG. 1 , the state when the second air inlet 202 is used for air intake is as shown in FIG. Figure 6 As shown in . As mentioned above, the air intake through the first air intake port 201 can ensure a better air intake effect, while the second air intake port 202 can prevent rain from entering the high-position air intake pipe when driving in rainy and snowy weather, so as to prevent damage to the air filter and even the engine.

[0057] The specific use of the wading hose structure of this embodiment can be found in the description below.

[0058] Embodiment 2

[0059] The present embodiment relates to a high-position air intake structure for a vehicle, which includes a high-position air intake pipe partially extending along the A-pillar 3 of the vehicle, and the top of the high-position air intake pipe has the wading throat structure of the high-position air intake pipe of the vehicle in the first embodiment. At the same time, the high-position air intake structure for a vehicle in the present embodiment also includes a control unit connected to the driving unit 8 located on the vehicle, and a trigger unit connected to the control unit located on the vehicle. Moreover, the trigger unit of the present embodiment is designed to be triggered by the outside world, and then the control unit responds to the trigger signal of the trigger unit to be able to output the external control signal for causing the driving unit 8 to operate.

[0060] Among them, see Figure 7As shown in , as a preferred implementation form, the control unit of this embodiment can be integrated into the vehicle body controller 12, and the trigger unit includes at least one of a touch switch 13 and a rain and snow sensing component 14 connected to the vehicle body controller 12.

[0061] At this time, the above-mentioned touch switch 13 can be, for example, a key switch or a button switch separately arranged on the vehicle dashboard, and the button switch is electrically connected to the vehicle body controller 12, so that when it is touched, the vehicle body controller 12 can obtain a trigger signal. The above-mentioned rain and snow sensing component 14 can generally adopt a rain sensor used in many vehicles, and the rain sensor is also electrically connected to the vehicle body controller 12. When the rain sensor detects rainfall, the vehicle body controller 12 obtains a trigger signal.

[0062] It should be noted that the touch switch 13 can also realize manual control of the action of the driving unit 8 in the air intake structure of this embodiment, while the rain and snow sensing component 14 can realize automatic control of the action of the driving unit 8. In actual applications, the manual mode is generally preferred to have a higher priority than the automatic mode, so that the driver can control the opening and closing of each air intake according to his own wishes on the basis of automatically opening and closing the air intake according to rain and snow weather.

[0063] In addition, in this embodiment, in addition to integrating the control unit into the vehicle body controller 12, a separate control device can also be set in the vehicle to control the overall intake structure. The touch switch 13 can be a physical button or a knob switch, or a virtual button displayed in the hollow screen of the vehicle, and the rain and snow sensor component 14 can share the same set of rain sensors with the automatic wiper assembly on the vehicle when it is specifically set.

[0064] When the vehicle high-position air intake structure of this embodiment is in use, its overall control method includes obtaining the external environment of the vehicle, and controlling the baffle 7 to switch between the first air intake port 201 and the second air intake port 202 according to the external environment of the vehicle.

[0065] Among them, in the above driving control of the baffle 7 according to the external environment of the vehicle, as mentioned above, at least when the external environment is rainy or snowy weather, the second air inlet 202 is opened and the first air inlet 201 is closed.

[0066] Specifically, when encountering rainy and snowy weather, the driver can operate the touch switch 13 to close the first air inlet 201 and open the second air inlet 202, thereby preventing rainwater from entering the snorkel and the air intake pipe. Alternatively, the vehicle body controller 12 can control the closing of the first air inlet 201 and the opening of the second air inlet 202 by using the detection of the rain and snow sensing component 14.

[0067] When there is no rain or snow, for example, when the weather is clear or only cloudy, the driver can operate the touch switch 13 again to close the second air inlet 202 and open the first air inlet 201 to ensure the air intake effect. Alternatively, the detection of the rain and snow sensor 14 can still be used to make the body controller 12 control the closing of the second air inlet 202 and the opening of the first air inlet 201.

[0068] In addition, it should be noted that the opening and closing of the two air inlets in this embodiment is not only based on the judgment of rainy and snowy weather, but in actual use, it can also be based on other situations where water drops or water flows fall, such as automatic car washing, and the two air inlets can be opened or closed with the same control logic. This also prevents water from entering the air intake pipe.

[0069] At the same time, in addition to selectively opening the first air inlet 201 or the second air inlet 202, the present embodiment can also be set to control the baffle 7 to be between the two air inlet positions when the weather is clear or cloudy, or even when it is raining or snowing, so that the first air inlet 201 and the second air inlet 202 are opened at the same time. In the use mode of opening the two air inlets at the same time, the specific position of the baffle 7 can be manually adjusted in the form of a knob, or several positions can be preset in the control unit for selection, which can be set according to needs during specific implementation.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
