[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0034] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0035] This disclosure provides a vehicle. The vehicle can be a small vehicle, a medium-sized vehicle, or a large vehicle. For example, the vehicle can be a conventional fuel vehicle, a pure electric vehicle, a hybrid electric vehicle, a fuel cell vehicle, a hydrogen engine vehicle, a natural gas vehicle, a range-extended electric vehicle, or a solar-powered vehicle, etc.

[0036] The vehicle may include a vehicle body, a controller, and an in-vehicle air conditioner. The in-vehicle air conditioner and controller are located in the vehicle body, and the controller is used to control the on / off state of the in-vehicle air conditioner. For example, when the driver inputs a command to turn on the air conditioner, the controller receives the command and controls the in-vehicle air conditioner to be turned on; when the driver inputs a command to turn off the air conditioner, the controller receives the command and controls the in-vehicle air conditioner to be turned off. The driver can input the command in ways including but not limited to: manually pressing the control button, voice input, and touching the vehicle's infotainment display panel.

[0037] The vehicle air conditioner may include an air conditioner body and an air intake structure. The air intake structure is connected to the air intake of the vehicle air conditioner body and can guide the air outside the vehicle cabin into the vehicle air conditioner body through the air intake of the vehicle air conditioner body, and finally into the vehicle cabin to regulate the temperature inside the vehicle cabin.

[0038] However, when a vehicle is wading through water, if the outside water level reaches the height of the vehicle's air conditioning intake structure (for example, if the outside water level is not less than one meter), water can flow into the vehicle's air conditioning unit through the air conditioning intake structure and eventually into the vehicle's cabin, which may damage the vehicle's electrical components and reduce the safety factor.

[0039] To solve the above problems, see Figure 1 , Figure 2 , Figure 4 In one embodiment of this disclosure, the vehicle air conditioning intake structure includes a housing 1, at least one waterproof door 2, and a drive assembly 3. The housing 1 has multiple cavities, with adjacent cavities connected by an air vent 14. At least one waterproof door 2 is disposed within at least one cavity. The drive assembly 3 is disposed in the housing 1 and connected to the waterproof door 2, for driving the waterproof door 2 to move, thereby blocking or opening at least one air vent 14.

[0040] In the embodiments of this disclosure, by providing a waterproof door 2 in the cavity, when the vehicle is wading through water, the drive assembly 3 can drive the waterproof door 2 to move, thereby blocking the air vent 14. This prevents water from flowing into the vehicle air conditioning unit through the air intake structure, reducing the possibility of water entering the vehicle cabin and improving vehicle safety. When the vehicle is not wading through water, the drive assembly 3 can drive the waterproof door 2 to move, opening the air vent 14. Outside air can then enter the vehicle air conditioning unit through the air vent 14, which is beneficial for the normal operation of the vehicle air conditioning's external circulation.

[0041] In one embodiment of this disclosure, there may be two cavities, which are connected by a vent 14. In other embodiments of this disclosure, there may be more than two cavities, such as three, four, or five, with adjacent cavities connected by a vent 14.

[0042] In one embodiment of this disclosure, each cavity and each air inlet 14 form an air guide channel, which can extend along a straight line, curve, broken line, or a combination of curve and broken line.

[0043] In one embodiment of this disclosure, a waterproof door 2 may be provided in one of the cavities, or waterproof doors 2 may be provided in each cavity; there is no limitation on this.

[0044] In one embodiment of this disclosure, see Figure 1 , Figure 2 , Figure 4 The housing 1 has two cavities, which are connected by an air duct 14. The housing 1 includes a top shell 11, a bottom shell 12, and a convex shell 13. The bottom shell 12 and the top shell 11 are fastened together to form one of the cavities, which has an air inlet. The convex shell 13 is integrally connected to the side of the bottom shell 12 away from the top shell 11, and has an air duct 14 and the other cavity. The end of the convex shell 13 away from the bottom shell 12 is connected to the air inlet of the vehicle air conditioning unit by bolts, snap-fits, or other means, and the cavity communicates with the air inlet of the vehicle air conditioning unit. It should be noted that "top shell 11" and "bottom shell 12" in this text are only distinguishing names and do not represent specific locations.

[0045] In one embodiment of this disclosure, see Figure 1 , Figure 2 A sealing ring 5 is provided at the end of the convex shell 13 away from the bottom shell 12. The material of the sealing ring 5 can be EPDM, so as to improve the sealing performance between the convex shell 13 and the vehicle air conditioner body.

[0046] In one embodiment of this disclosure, see Figure 1 and Figure 3The drive assembly 3 may include a drive member 31, a screw 32, and a transmission member 33. The drive member 31 is located on the top shell 11 and drives the transmission member 33 to rotate. The transmission member 33 is rotatably located on the top shell 11. The screw 32 passes through the transmission member 33 and extends into the cavity. The screw 32 is rotatably connected to the waterproof door 2 and threadedly connected to the transmission member 33. In one example, the drive member 31 may be a device with driving force, such as a motor or a tilting cylinder. The motor may be a DC motor and meet the IP67 dustproof and waterproof rating. The motor has an output shaft, and a drive gear is coaxially fixedly connected to the output shaft, which extends axially along the screw 32. The transmission member 33 may be a driven gear, meshing with and coaxially arranged with the drive gear. Both the drive gear and the driven gear are spur gears. In another example, the drive gear and the driven gear may be bevel gears. The axis of the driven gear is parallel to the axis of the screw 32, and the axis of the drive gear is perpendicular to the axis of the screw 32. The output shaft is coaxially connected to the drive gear. Thus, the driving component 31 can drive the transmission component 33 to rotate, and the transmission component 33 drives the screw 32 to rotate, so that the screw 32 can drive the waterproof door 2 to move along the axial direction of the screw 32, so as to block or open the air vent 14.

[0047] In one embodiment of this disclosure, see Figure 1 , Figure 3 A limiting member 34 is fixedly connected to the top shell 11. The limiting member 34 has a limiting portion 341, and the transmission member 33 is limited between the limiting portion 341 and the top shell 11. For example, there can be multiple limiting members 34, which are distributed circumferentially along the transmission member 33. The limiting member 34 can be a limiting post connected to the top shell 11, with the limiting portion 341 located on the side of the limiting post away from the top shell 11. The transmission member 33 is located between the limiting portion 341 and the top shell 11, allowing the transmission member 33 to rotate on the top shell 11. The transmission member 33 can contact the limiting portion 341 or have a gap between it and the limiting portion 341, and the gap can be less than half the axial dimension of the transmission member 33. In this way, the transmission member 33 and the top shell 11 can be rotated through the limiting member 34.

[0048] In one embodiment of this disclosure, the top shell 11 may have a receiving cavity in which the rotating member can rotate to improve the stability of the rotating member during rotation.

[0049] In one embodiment of this disclosure, the drive assembly 3 includes a drive member 31, a screw 32, and a transmission member 33. The drive member 31 is disposed on the top shell 11 and is used to drive the screw 32 to rotate; the transmission member 33 is connected to the waterproof door 2, the screw 32 extends into the cavity and passes through the transmission member 33 and the waterproof door 2, the screw 32 is rotatably connected to the shell 1 and threadedly connected to the transmission member 33. Thus, the drive member 31 can drive the screw 32 to rotate, and the screw 32 drives the waterproof door 2 to move axially along the screw 32 through the transmission member 33, so as to block or open the air vent 14 of the waterproof door 2.

[0050] In one embodiment of this disclosure, see Figure 4 The drive assembly 3 includes a drive component 31 and a screw 32. The drive component 31 is located on the top shell 11 and is used to drive the screw 32 to rotate. The screw 32 is threadedly connected to the waterproof door 2, extends into the cavity and passes through the waterproof door 2, and is rotatably connected to the shell 1. In other words, the drive assembly 3 does not have a transmission component 33, and the screw 32 is threadedly connected to the waterproof door 2. This reduces the number of parts and lowers costs.

[0051] In one embodiment of this disclosure, the vehicle body may be equipped with a water level sensor. When the water level sensor detects a water level, it sends a blocking signal to the controller. Based on the blocking signal, the controller activates the drive unit 31 to block the vent 14 using the waterproof door 2. Conversely, when the water level sensor does not detect a water level, it sends an opening signal to the controller. Based on the opening signal, the controller activates the drive unit 31 to open the vent 14 using the waterproof door 2. The water level sensor is located at a height of no more than one meter above the vehicle body. Thus, when the vehicle is wading through water, the water level sensor sends a blocking signal to the controller, which then activates the drive unit 31 to block the vent 14 using the waterproof door 2, eliminating the need for manual control of the waterproof door 2 and improving automation.

[0052] In one embodiment of this disclosure, see Figure 1 , Figure 2 , Figure 4 A sealing ring 4 is provided on the side of the waterproof door 2 near the air vent 14. The area of ​​the sealing ring 4 is larger than the area of ​​the air vent 14, and the area of ​​the waterproof door 2 is larger than the area of ​​the sealing ring 4. The material of the sealing ring 4 can be EPDM. In this way, the sealing performance of the waterproof door 2 can be improved, reducing the possibility of water flowing into the air vent 14.

[0053] In one embodiment of this disclosure, the drive assembly 3 further includes a guide for guiding the waterproof door 2 along the axial direction of the screw 32. In a first example, see [link to first example]. Figure 1 , Figure 2 , Figure 4The guide component includes at least one guide rod 35, which is fixed in the cavity containing the waterproof door 2 and arranged parallel to the screw 32. Multiple guide rods 35 can be distributed circumferentially along the air inlet 14. The guide rods 35 penetrate the waterproof door 2 and slide against it. The waterproof door 2 may have a sliding sleeve, which is fitted onto and slides against the guide rods 35. Thus, the sliding engagement between the guide rods 35 and the waterproof door 2 allows the screw 32 to drive the waterproof door 2 to move axially along the screw 32, thereby achieving the sealing and opening of the air inlet 14.

[0054] In the second example, the guide may include at least one slider connected to the periphery of the waterproof door 2. A groove is provided on the inner wall of the cavity containing the waterproof door 2, extending along the axial direction of the screw 32. The slider slides into the groove. Thus, the sliding engagement of the slider and the groove allows the screw 32 to drive the waterproof door 2 to move axially along the screw 32, thereby achieving the sealing and opening of the air vent 14.

[0055] In the third example, the guide may include at least one limiting rod, which is fixed in the cavity and parallel to the screw 32. The waterproof door 2 has a limiting groove, and the limiting rod slides into the limiting groove. Thus, the sliding engagement between the limiting groove and the limiting rod allows the screw 32 to drive the waterproof door 2 to move axially along the screw 32, thereby achieving the sealing and opening of the air vent 14.

[0056] In the fourth example, the guide may include at least one protrusion, which may be located on the side wall of the cavity where the waterproof door 2 is located. The protrusion extends axially along the screw 32, and the periphery of the waterproof door 2 may be provided with a groove, with the protrusion and the groove slidingly engaged. In this way, the sliding engagement between the protrusion and the groove allows the screw 32 to drive the waterproof door 2 to move axially along the screw 32, thereby achieving the sealing and opening of the air vent 14.

[0057] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
