[0001] This utility model belongs to the technical field of waterproof valves for automotive air intake channels, specifically relating to an electrically controlled active sealing waterproof valve for automotive fresh air channels. Background Technology

[0002] In a car's air conditioning system, the air intake and exhaust vents form the ventilation system, responsible for delivering processed (temperature and humidity controlled, purified) airflow into the cabin to perform functions such as ventilation, cooling, heating, defrosting, defogging, and air purification. However, when a car is wading through water, the connection between the air conditioning intake and the cabin often allows water from outside to quickly enter the cabin, especially during extreme driving, emergency wading, or when the car has fallen into water due to an accident. Utility Model Content

[0003] The purpose of this invention is to provide an electronically controlled active sealing waterproof valve for automotive fresh air ducts, aiming to solve the above-mentioned problems.

[0004] This utility model is mainly achieved through the following technical solutions:

[0005] An electronically controlled active sealing waterproof valve for automotive fresh air ducts includes a valve body and a valve mechanism. The valve body has a first air inlet on the side near the vehicle body and a second air inlet communicating with the atmosphere on the free side of the valve body. The valve mechanism is installed inside the valve body and is used to open or close the first air inlet.

[0006] The valve mechanism includes a drive mechanism, a valve, a drive arm, a hinge arm shaft, and a hinge housing shaft. The valve is located inside the valve body and on one side of the first air inlet. One end of the valve is hinged to the valve body via the hinge housing shaft, and the other end of the valve is hinged to one side of the drive arm via the hinge arm shaft. A drive shaft hinged to the valve body is fixedly installed on the other side of the drive arm. The drive mechanism is used to drive the drive shaft to rotate, so that the valve opens or closes the first air inlet. The hinge arm shaft is slidably connected to the side wall of the valve.

[0007] To better realize this utility model, the valve body further includes a front housing and a rear housing connected to each other, and the rear housing is provided on the side of the front housing near the vehicle body. The front housing and the rear housing are respectively provided with a second air inlet and a first air inlet.

[0008] To better realize this utility model, one end of the valve is further hinged to the rear housing via a hinged housing shaft, and the drive shaft is hinged to the front housing.

[0009] To better realize this utility model, the driving mechanism is further described as a rotary actuator, which is installed on the outside of the front housing, and the driving end of the rotary actuator extends into the interior of the front housing and is connected to the drive shaft.

[0010] To better realize this utility model, the bottom of the front housing is provided with a drainage cavity, and a drainage port cover is provided on one side of the drainage cavity.

[0011] To better realize this utility model, the first connecting rod is symmetrically arranged at both ends of one side of the drive arm, and the two side walls of the valve are respectively provided with hinge arm shafts, and the free end of the first connecting rod is hinged to the hinge arm shaft.

[0012] To better realize this utility model, a second connecting rod is symmetrically arranged on the other side of the drive arm, and the drive shaft is fixedly connected to the second connecting rod.

[0013] To better realize this utility model, the side wall of the valve is further provided with a sliding groove along the length direction corresponding to the hinge arm shaft.

[0014] To better realize this utility model, a soft rubber sealing strip is further provided on the periphery of the valve near the first air inlet, and sponge strips are respectively provided on the periphery of the first air inlet and the second air inlet.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model sets a valve inside the valve body near the first air inlet, and closes the first air inlet inside the valve body by driving the valve. When water enters the valve body, the water exerts pressure on the valve, further strengthening the sealing of the first air inlet and improving the reliability of use. This utility model arranges an electrically controlled valve mechanism between the cab and the air intake channel to prevent water from entering the cab when the vehicle is wading, thereby further improving the off-road and safety performance of the vehicle. This utility model has a simple and reliable structure, occupies a compact space, does not affect the normal air intake function, responds quickly, and has a short operating time; and effectively utilizes water pressure, making the valve seal more tight under the action of water pressure.

[0017] (2) The drive arm in this utility model is a linkage mechanism, which is simple and reliable. In addition, the valve structure cleverly utilizes water pressure, that is, the greater the water pressure, the better the sealing effect, avoiding the risk of valve failure due to water pressure. When not in use, the valve is retracted to one side inside the front housing, which is compact and optimizes the overall space utilization of the structure. This utility model has a rapid operation and response time, stable function, and controllable cost, and can protect vehicles with wading capabilities. Attached Figure Description

Detailed Implementation

[0026] Example 1:

[0027] An electronically controlled active sealing waterproof valve for automotive fresh air ducts includes a valve body 300 and a valve mechanism, such as... Figures 1-3 As shown, a firewall 100, a front ventilation cover 200, and a valve body 300 are provided on the front side of the vehicle body. The valve body 300 has a first air inlet on the side closest to the vehicle body, and a second air inlet communicating with the atmosphere on the free side of the valve body 300; a valve mechanism is provided inside the valve body 300, which is used to open or close the first air inlet;

[0028] The valve mechanism includes a drive mechanism, a valve 3, a drive arm 4, a hinge arm shaft 6, and a hinge housing shaft 7. The valve 3 is disposed inside the valve body 300 and located on one side of the first air inlet. One end of the valve 3 is hinged to the valve body 300 via the hinge housing shaft 7, and the other end of the valve 3 is hinged to one side of the drive arm 4 via the hinge arm shaft 6. A drive shaft 5, which is hinged to the valve body 300, is fixedly installed on the other side of the drive arm 4. The drive mechanism is used to drive the drive shaft 5 to rotate, so that the valve 3 opens or closes the first air inlet. The hinge arm shaft 6 is slidably connected to the side wall of the valve 3.

[0029] Preferably, such as Figure 6 As shown, the drive arm 4 has first connecting rods symmetrically arranged at both ends on one side, and second connecting rods symmetrically arranged at both ends on the other side. The valve 3 has sliding grooves on both side walls, and a hinged arm shaft 6 is slidably arranged inside the sliding grooves. The free end of the hinged arm shaft 6 is hinged to the first connecting rod. The drive shaft 5 passes through the two second connecting rods sequentially, and the drive shaft 5 is fixedly connected to the second connecting rods.

[0030] Preferably, such as Figure 2 , Figure 3 and Figure 7 As shown, a soft rubber sealing strip 13 is provided on the periphery of the valve 3 near the first air inlet, and a sponge strip 12 is provided on the periphery of the first air inlet and the second air inlet, respectively.

[0031] The drive arm 4 in this invention is a linkage mechanism, which is simple and reliable. Furthermore, the valve 3 cleverly utilizes water pressure; the higher the water pressure, the better the sealing effect, thus avoiding the risk of valve 3 failure due to water pressure. When not in use, the valve 3 retracts to one side inside the front housing 1, resulting in a compact arrangement and optimized overall space utilization. This invention offers rapid actuation and response times, stable function, and controllable cost, providing protection for vehicles with wading capabilities.

[0032] Example 2:

[0033] An electronically controlled active sealing waterproof valve for automotive fresh air ducts, such as Figures 1-3 As shown, an electrically controlled active sealing valve is arranged between the cab and the air intake passage to prevent water from entering the cab when the vehicle is wading through water, thereby further improving the vehicle's off-road and safety performance. This invention features a simple and reliable arrangement, rapid response, and short operating time; it also effectively utilizes water pressure, resulting in a more tight seal for valve 3 under water pressure. The valve 3 device occupies a compact space and does not affect normal air intake function.

[0034] like Figure 4 As shown, the electrically controlled sealing valve 3 specifically comprises a front housing 1, a rear housing 2, a valve 3, a drive arm 4, a drive shaft 5, a hinge arm shaft 6, a hinge housing shaft 7, a buffer pin 8, an actuator 9, a drain cover 10, screws 11, etc., and a sponge strip 12.

[0035] The connection relationships between the components are as follows: Figures 2-7 As shown, the front housing 1 and the rear housing 2 are welded together. The drive arm 4 and the valve 3 are hinged together by the hinge arm shaft 6; the rear housing 2 is hinged to the valve 3 by the hinge housing shaft 7; the drive shaft 5 passes through the front housing 1 and the drive arm 4, the drive shaft 5 is hinged to the front housing 1, and is assembled with the drive arm 4 as a whole.

[0036] Preferably, the actuator 9 is assembled into one piece with the hexagonal shaft of the drive shaft 5 through a hexagonal hole; the actuator 9 is connected to the front housing 1 by screws 11.

[0037] Preferably, the drain cover 10 is hinged to the front housing 1; the sponge strip 12 is bonded to the front housing 1 as a whole.

[0038] This product, based on its working principle, is mainly divided into a housing and a valve mechanism; such as Figure 2 As shown, valve 3 is fully open when the product is in standby mode; Figure 3 As shown, when actuator 9 is energized, the integrated structure consisting of drive shaft 5, drive arm 4, and hinged arm shaft 6 drives valve 3 to rotate along hinged housing shaft 7; finally, valve 3 fits tightly against rear housing 2. At this point, when actuator 9 is de-energized, actuator 9 self-locks to keep valve 3 closed. If water is injected into the cavity of front housing 1 at this time, the water pressure will apply pressure to rear housing 2 through valve 3, thereby making the sealing effect more reliable. The opening of valve 3 is the reverse of the above process.

[0039] This utility model adopts a linkage mechanism, which is simple and reliable. Figure 7 As shown, the valve body 3 is made of rigid plastic to ensure good rigidity and no deformation, while the soft rubber uses a micro-foaming process to ensure reliable sealing and waterproofing. Furthermore, the valve 3 structure cleverly utilizes water pressure; the higher the water pressure, the better the sealing effect, avoiding the risk of valve 3 failure due to water pressure. Finally, when not in use, the valve 3 retracts to one side of the front housing 1, resulting in a compact arrangement and optimizing the overall space utilization. In summary, this product has rapid operation and response time, stable function, and controllable cost, providing protection for vehicles with wading capabilities.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
