Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning design, and in particular to a waterproof structure for an automotive air conditioning inlet and a vehicle thereof. Background Technology

[0002] Automotive air conditioning is a ventilation system used to adjust and control the temperature, humidity, air cleanliness, and airflow inside a car cabin to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and playing an important role in ensuring safe driving.

[0003] The ventilation cover is a black plastic piece located between the windshield and the engine cover of a car. Its main function is to drain water flowing under the windshield through drainage holes to the bottom of the car to prevent water accumulation. The cover itself has dense ventilation holes to provide outside air to the air conditioning system. It also integrates the function of shielding the wiper nozzles from the wipers.

[0004] Car air conditioners and ventilation covers are usually used together to effectively prevent water from leaking into the air intake during rain or car washes. However, the cover and the glass sealant are connected by a snap-fit ​​structure. Due to manufacturing errors or aging and deformation of parts, it is extremely difficult to achieve an absolute seal. This can easily lead to water dripping into the air intake, causing the air conditioner to become moldy or even damaging the blower. This is a major problem in after-sales service.

[0005] In related technologies, a protective structure for an air conditioning inlet in a car is disclosed, wherein at least one water baffle is provided at the edge of the air conditioning inlet; the water baffle is located in the area between the blocking platform and the blocking flange. A lower front cabin trim panel is provided above the front side panel; the lower front cabin trim panel has an air vent; a water-blocking drape is provided at the edge of the air vent; and a sealing sponge strip is provided at the connection between the lower front cabin trim panel and the windshield. However, in this solution, the side water baffle can only prevent lateral water flow from entering the air conditioning inlet, and is ineffective against Z-axis raindrops. Additionally, an air conditioning inlet water baffle assembly and a car are also disclosed, wherein a water baffle is provided at the air conditioning inlet, and three sides of the water baffle are fixedly connected to a water channel. The water baffle and the air conditioning inlet form an air intake channel, with the air conditioning inlet of the air intake channel facing the front windshield crossbeam, restricting the flow of liquid from the water channel into the air conditioning inlet. However, the patent's side metal enclosure, designed to prevent rainwater from entering the air conditioner's air intake, is ineffective against raindrops falling in the z-direction. Summary of the Invention

[0006] This invention provides a water-proof structure for an automotive air conditioning inlet to solve the problem in related technologies where water drips into the air conditioning inlet, causing the air conditioner to mold or even damage the blower.

[0007] In a first aspect, a water-proof structure for an automotive air conditioning inlet is provided, comprising: a glass assembly; a ventilation cover plate, wherein the ventilation cover plate is engaged with a retaining strip of the glass assembly via a claw, and a first water-blocking rib is provided on the ventilation cover plate near the claw; a water channel fixed to the ventilation cover plate, wherein an air conditioning inlet is provided on the water channel, and a waterproof cover is installed on the air conditioning inlet, wherein the first water-blocking rib is located above the waterproof cover, and the length of the first water-blocking rib is greater than the length of the waterproof cover. In this embodiment, the glass assembly and the ventilation cover are assembled by a snap-fit ​​structure, and there is a gap at the connection between the two. Raindrops will flow into the gap from the glass assembly and then slide down the inside of the ventilation cover. An air conditioning inlet is left in the middle area of ​​the water channel. The waterproof cover is fixed to the water channel on both sides by bolts. Since a first water-blocking rib is added to the inside of the ventilation cover, the first water-blocking rib extends along the Y direction of the whole vehicle and its length crosses the air conditioning inlet. When the raindrops move along the inside of the ventilation cover, they will be guided to drip onto the waterproof cover when they reach the area of ​​the first water-blocking rib. The top of the waterproof cover is provided with a ridge groove, so that the raindrops dripping in the Z direction can flow to both sides of the waterproof cover, preventing the raindrops from seeping into the air conditioning inlet.

[0008] In some embodiments, the top of the waterproof cover is provided with a ridge groove, the bottom of the ridge groove has an inclined plate surface, and the opposite sides of the ridge groove are respectively provided with a front baffle and a rear baffle. In this embodiment, the top of the waterproof cover is provided with a ridge groove, which includes two plate surfaces forming a certain angle. After raindrops fall into the ridge groove, they will move along the inclined plate surface of the ridge groove until they flow out of the waterproof cover, thereby guiding the falling raindrops to both sides of the waterproof cover and preventing raindrops from seeping into the air conditioner inlet; the opposite sides of the ridge groove are respectively provided with a front baffle and a rear baffle, which together with the ridge groove form a U-shaped groove, allowing raindrops to slide along this groove to both sides of the waterproof cover, preventing raindrops from seeping into the air conditioner inlet.

[0009] In some embodiments, the ventilation cover has wiper holes, and a second water-retaining rib is provided on the ventilation cover around the outside of the wiper holes. In this embodiment, the ventilation cover has wiper holes, in which a wiper shaft is installed. The second water-retaining rib extends downward from the bottom of the ventilation cover and is semi-circular, arranged around the outside of the wiper holes. Regardless of how the vehicle is tilted in the Y-direction, raindrops will be guided and dripped off by the semi-circular water-retaining rib, thereby preventing them from flowing horizontally into the air conditioning intake area.

[0010] In some embodiments, a sheet metal stop is provided near the air conditioner inlet of the drainage channel, and the sheet metal stop extends in a direction perpendicular to the surface of the drainage channel. In this embodiment, the sheet metal stop extends upward from the surface of the drainage channel, serving as a barrier. Raindrops near the air conditioner inlet are prevented from entering from around the inlet due to the double protection of the sheet metal stop and the compressed waterproof foam.

[0011] In some embodiments, waterproof foam is compressed between the waterproof cover and the water channel. In this embodiment, the bottom of the waterproof cover has an outwardly extending plate, and waterproof foam is compressed between the extended plate and the water channel. The waterproof foam is in a compressed state, providing excellent sealing performance and preventing raindrops from flowing inward. Furthermore, the waterproof foam has excellent resistance to compression deformation, effectively protecting the components from shock. Raindrops near the air conditioner inlet are prevented from entering from around the air conditioner inlet due to the protection of the compressed waterproof foam.

[0012] In some embodiments, the waterproof cover has an air conditioning inlet on the side near the air conditioning inlet. In this embodiment, to ensure sufficient air intake for the air conditioning inlet, the waterproof cover must have enough openings. The waterproof cover has a total of 6 openings, with two openings on the side near the air conditioning inlet, two openings on the side perpendicular to the air conditioning inlet, and two openings on the other side perpendicular to the air conditioning inlet. Simulation calculations show that this is sufficient to ensure the air conditioning intake.

[0013] In some embodiments, the waterproof cover has an air conditioning inlet on one side perpendicular to the air conditioning inlet. In this embodiment, to ensure sufficient air intake at the air conditioning inlet, the waterproof cover must have enough openings. The waterproof cover has a total of six openings: two on the side closest to the air conditioning inlet, two on the side perpendicular to the air conditioning inlet, and two on the other side perpendicular to the air conditioning inlet. Simulation calculations show this is sufficient to guarantee the air conditioning intake.

[0014] In some embodiments, one end of the waterproof cover has a stepped recessed platform with a groove. In this embodiment, the recessed platform is located at the end of the ridge groove, forming a step with the ridge groove. The recessed platform slopes downward, and the groove is located at the lower part of the recessed platform. The groove is recessed from the surface of the recessed platform towards the height. After raindrops are collected from the ridge groove, they flow onto the recessed platform, then flow down the platform into the groove, and finally flow from the groove to the side of the waterproof cover, thus guiding the flow and ensuring a clear path to prevent raindrops from entering the air conditioning inlet.

[0015] Secondly, a vehicle is provided that includes the aforementioned waterproof structure for the automotive air conditioning inlet.

[0016] In some embodiments, the first water-retaining rib extends along the width direction of the vehicle.

[0017] The beneficial effects of the technical solution provided by this invention include:

[0018] This invention provides a water-proof structure for an automotive air conditioning inlet and a vehicle. By adding a water-blocking rib on the inner side of the ventilation cover, which extends across the air conditioning inlet (Y direction of the vehicle), raindrops falling onto the water-blocking rib area are diverted and drip onto the waterproof cover. This allows raindrops falling in the Z direction to flow to both sides of the waterproof cover, preventing raindrops from seeping into the air conditioning inlet. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The drainage method for heavy rainfall or car washing is conventional because the ventilation cover has drainage holes on both sides, and the water flows directly to both ends of the drainage channel. This application will not elaborate on the relevant content. The focus is on solving the problem of water seepage in a small area of ​​the ventilation cover, which leads to water droplets dripping from the back of the wiper cover into the air conditioning intake due to durability failure.

[0032] This invention provides a water-proof structure for an automotive air conditioning inlet, which solves the problem in related technologies where water drips into the air conditioning inlet, causing mold growth in the air conditioner or even damage to the blower.

[0033] like Figure 1 and Figure 7 The diagram shows the assembly of the glass assembly 1 and the ventilation cover 2 in a real vehicle configuration. It provides a water-proof structure for an automotive air conditioning inlet, which may include: a glass assembly 1; a ventilation cover 2, which is engaged with the locking strip 101 of the glass assembly 1 via a claw 203, and a first water-blocking rib 204 located near the claw 203; and a water channel 3 fixed to the ventilation cover 2, on which an air conditioning inlet 301 is provided, and a waterproof cover 4 is installed. The first water-blocking rib 204 is located above the waterproof cover 4, and the length of the first water-blocking rib 204 is greater than the length of the waterproof cover 4.

[0034] In this embodiment, the glass assembly 1 and the ventilation cover 2 are assembled by a snap-fit ​​structure, and there is a gap at the connection between the two. Raindrops will flow into the gap from the glass assembly 1 and then slide down along the inner side of the ventilation cover 2. The middle area of ​​the water channel 3 has an air conditioning inlet 301. The waterproof cover 4 is fixed to the water channel 3 on both sides by bolts 5. Since a first water-blocking rib 204 is added to the inner side of the ventilation cover 2, the first water-blocking rib 204 is straight and extends along the Y direction of the whole vehicle and its length crosses the air conditioning inlet. When the raindrops move along the inner side of the ventilation cover 2, they will be guided to drip onto the waterproof cover 4 when they reach the area of ​​the first water-blocking rib 204. The top of the waterproof cover 4 is provided with a ridge groove 404, so that the raindrops dripping in the Z direction can flow to both sides of the waterproof cover 4, preventing the raindrops from seeping into the air conditioning inlet 301.

[0035] In another embodiment, the first water-blocking rib 204 can also be curved and extend along the Y direction of the whole vehicle, which can easily avoid other components inside the ventilation cover 2. The length of the first water-blocking rib 204 needs to cross the air conditioning inlet. When raindrops move along the inside of the ventilation cover 2, they will be guided to drip onto the waterproof cover 4 when they reach the area of ​​the first water-blocking rib 204. The top of the waterproof cover 4 is provided with a ridge groove 404, so that the raindrops dripping in the Z direction can flow to both sides of the waterproof cover 4, preventing raindrops from seeping into the air conditioning inlet 301.

[0036] See Figure 3 and Figure 4 As shown, in some embodiments, the top of the waterproof cover 4 may be provided with a ridge groove 404, the bottom of the ridge groove 404 has an inclined plate surface, and the opposite sides of the ridge groove 404 are respectively provided with a front baffle 403 and a rear baffle 402.

[0037] In this embodiment, the top of the waterproof cover 4 is provided with a ridge groove 404. The ridge groove 404 includes two plates forming a certain angle. After raindrops fall into the ridge groove 404, they will move along the inclined plates of the ridge groove 404 until they flow out of the waterproof cover 4, thereby guiding the falling raindrops to both sides of the waterproof cover 4 and preventing raindrops from seeping into the air conditioner inlet 301. The opposite sides of the ridge groove 404 are respectively provided with a front baffle 403 and a rear baffle 402. The front baffle 403 and the rear baffle 402 form a U-shaped groove with the ridge groove 404. Raindrops can slide along this groove to both sides of the waterproof cover 4, preventing raindrops from seeping into the air conditioner inlet 301.

[0038] See Figure 8As shown, in some embodiments, waterproof foam 405 is pressed between the waterproof cover 4 and the water channel 3. In this embodiment, the bottom of the waterproof cover 4 is provided with an outwardly extending plate, and the extended plate and the water channel 3 are pressed together with waterproof foam 405. The waterproof foam 405 is in a compressed state and has good sealing performance, which can prevent raindrops from flowing inward. Moreover, the waterproof foam has good resistance to compression deformation and can effectively protect the accessories from shock. Raindrops near the air conditioner inlet 301 of the water channel 3 are protected by the compressed waterproof foam 405, which prevents raindrops 6 from entering from all sides of the air conditioner inlet 301.

[0039] In another embodiment, a waterproof coating may also be applied between the waterproof cover 4 and the water channel 3. The waterproof coating is not easily corroded by rainwater and has a longer service life. The waterproof coating has good sealing performance, which can prevent raindrops from flowing in. Raindrops near the air conditioner inlet 301 of the water channel 3 are protected by the waterproof coating, so that raindrops 6 cannot enter from all sides of the air conditioner inlet 301.

[0040] In another embodiment, waterproof adhesive can also be applied between the waterproof cover 4 and the water trough 3. The waterproof adhesive can fix the waterproof cover 4 to the water trough 3 while also serving a waterproof function. The waterproof coating has excellent sealing performance, which can prevent raindrops from flowing in. Raindrops near the air conditioner inlet 301 of the water trough 3 are protected by the waterproof adhesive, preventing raindrops 6 from entering from all sides of the air conditioner inlet 301.

[0041] See Figure 8 As shown, in some embodiments, the water trough 3 is provided with a sheet metal stop 302 near the air conditioner inlet 301. The sheet metal stop 302 extends in a direction perpendicular to the surface of the water trough 3. In this embodiment, the sheet metal stop 302 extends upward from the surface of the water trough 3, which serves to block the flow. Raindrops near the air conditioner inlet 301 are prevented from entering from all sides of the air conditioner inlet 301 due to the double protection of the sheet metal stop 302 and the compressed waterproof foam 405.

[0042] In another embodiment, waterproof foam, waterproof adhesive, or waterproof coating can also be provided at the position of the water channel 3 near the air conditioner air inlet 301. The waterproof foam, waterproof adhesive, or waterproof coating plays a role in blocking water. Because of the protection of the waterproof foam, waterproof adhesive, or waterproof coating, raindrops 6 near the air conditioner air inlet 301 cannot enter from all sides of the air conditioner air inlet 301.

[0043] See Figure 3 and Figure 4As shown, in some embodiments, the waterproof cover 4 has a waterproof cover air conditioner inlet 401 on the side near the air conditioner inlet 301, and a waterproof cover air conditioner inlet 401 on the side perpendicular to the air conditioner inlet 301. In this embodiment, to ensure sufficient air intake of the air conditioner inlet 301, the waterproof cover 4 must have sufficient openings. The waterproof cover has a total of 6 openings: 401a, 401b, 401c, 401d, 401e, and 401f. Among them, the waterproof cover 4 has two openings, 401a and 401c, on the side near the air conditioner inlet 301; two openings, 401b and 401d, on the side perpendicular to the air conditioner inlet 301; and two openings, 401e and 401f, on the other side perpendicular to the air conditioner inlet 301. Simulation calculations show that this is sufficient to ensure the air intake of the air conditioner.

[0044] See Figure 3 and Figure 4 As shown, in some embodiments, one end of the waterproof cover 4 is provided with a stepped platform 406, and the platform 406 is provided with a groove 407. In this embodiment, the platform 406 is located at the end of the ridge groove 404, and the platform 406 and the ridge groove 404 form a step. The platform 406 is inclined downward, and the groove 407 is located at the lower part of the platform 406. The groove 407 is recessed from the surface of the platform 406 in the height direction. After the raindrops are collected by the ridge groove 404, they flow onto the platform 406, and then flow down the platform 406 into the groove 407. Finally, they flow from the groove 407 to the side of the waterproof cover 4, which plays a guiding role. The path is clear and prevents raindrops from entering the air conditioner inlet 301.

[0045] See Figure 5 As shown, in some embodiments, the ventilation cover 2 is provided with a wiper hole 201, and a second water-blocking rib 202 is provided around the outside of the wiper hole 201 on the ventilation cover 2. In this embodiment, the ventilation cover 2 is provided with a wiper hole 201, and a wiper shaft 7 is installed in the wiper hole 201. The second water-blocking rib 202 extends downward from the bottom of the ventilation cover 2. The second water-blocking rib 202 is semi-circular and is arranged around the outside of the wiper hole 201. No matter how the vehicle is tilted in the Y direction, the raindrops 6 will be diverted and dripped by the semi-second water-blocking rib 202, thereby preventing them from flowing horizontally into the air conditioning inlet 301 area.

[0046] In another embodiment, the second water-blocking rib 202 can also be circular and arranged around the outer side of the wiper hole 201, so that the water blocking angle is more comprehensive. No matter how the vehicle is tilted in the Y direction, the raindrops 6 will be guided and dripped off by the second water-blocking rib 202, thereby preventing them from flowing across the air conditioning inlet 301 area.

[0047] In another embodiment, the second water-blocking rib 202 can also be polygonal and arranged around the outer side of the wiper hole 201, so that the water blocking angle is more comprehensive. No matter how the vehicle is tilted in the Y direction, the raindrops 6 will be guided and dripped off by the polygonal second water-blocking rib 202, thereby preventing them from flowing across the air conditioning inlet 301 area.

[0048] In summary, to address the issue of rainwater entering the air conditioning inlet 301 laterally (i.e., along the Y-axis of the vehicle), the air conditioning inlet 301 is surrounded by flanges, and the bottom of the waterproof cover 4 has sealing foam. Bolts 5 are used to tighten and press the air conditioning inlet 301 together, creating a double-layer protective barrier that prevents raindrops from entering laterally. Simultaneously, the wiper holes 201 on the ventilation cover 2 have water-blocking ribs to prevent rainwater from seeping to the back of the cover and flowing towards the air conditioning inlet 301. Similarly, the ventilation cover 2 has a first water-blocking rib on its main surface to intercept raindrops that seep to the back, allowing them to flow down from the rib. Furthermore, a waterproof cover 4 is installed in the air conditioning inlet 301 area, with a ridge-like drainage channel at the top and water-blocking ribs on both sides to divert raindrops outside the waterproof cover 4. This design is unaffected by the vehicle's parking or tilting position, thus fundamentally preventing raindrops from seeping into the air conditioning inlet through the cover.

[0049] See Figure 1 and Figure 2 As shown, a vehicle provided in an embodiment of the present invention may include the aforementioned anti-water leakage structure for the automotive air conditioning inlet. The vehicle may also implement any embodiment of the aforementioned anti-water leakage structure for the automotive air conditioning inlet.

[0050] The first water-blocking rib 204 extends along the width of the vehicle. Because the first water-blocking rib 204 is added inside the ventilation cover 2, and extends along the Y-direction of the vehicle, its length spans the air conditioning inlet, when raindrops move along the inner side of the ventilation cover 2, they are guided to drip onto the waterproof cover 4 when they reach the area of ​​the first water-blocking rib 204. The top of the waterproof cover 4 has a ridge groove 404, which allows raindrops dripping in the Z-direction to flow to both sides of the waterproof cover 4, preventing raindrops from seeping into the air conditioning inlet 301. Therefore, a new structural approach is provided. By combining the rib structure of the ventilation cover 2 with the high airflow design of the waterproof cover 4, the problem of lateral and Z-direction raindrops at the air conditioning inlet can be effectively avoided. Based on thorough research, this innovative approach solves the problem of water ingress into the air conditioning system. It is simple to operate, low in cost, and has significant promotional and application value.

[0051] Through on-vehicle rain camera tracking, it was found that the source of water seepage mainly came from the assembly gap between the glass retainer 101 and the retainer 203, such as... Figure 6 and Figure 7As shown, raindrops 6 will seep along the outer side of the glass assembly into the inner side of the ventilation cover 2. A first water-blocking rib 204 is added to the inner side of the ventilation cover 2, its length extending across the air conditioning inlet 301 (in the Y direction of the vehicle). When raindrops 6 slide into the area of ​​the first water-blocking rib 204, they will be diverted into the ridge groove 404 of the waterproof cover 4. Simultaneously, front and rear baffles 402 and 403 are located on both sides of the ridge groove 404, forming a U-shaped backflow channel to prevent raindrops 6 from seeping into the air conditioning inlet 401 of the waterproof cover. The trajectory of raindrops 6 is as follows... Figure 6 As shown, the raindrops flowed to both sides of the waterproof cover. Regardless of how the vehicle was parked at an angle, the raindrops 6 would not cross the range of the first water-blocking rib 204.

[0052] In addition, there is another source of water seepage from the horizontal (Y-direction) direction of the wiper hole 201. Similarly, a semi-second water-blocking rib 202 is made on the inner side of the ventilation cover 2 near the wiper hole 201, such as... Figure 5 As shown, regardless of how the vehicle is tilted in the Y direction, raindrops 6 will be diverted by the second water-blocking rib 202 to prevent them from flowing horizontally into the air conditioning inlet 301 area.

[0053] like Figure 8 As shown, raindrops near the air conditioner inlet 301 in the water channel 3 cannot enter from all sides of the air conditioner inlet 301 because of the double protection of the sheet metal stop 302 and the compressed waterproof foam 405.

[0054] In summary, the structural solution fundamentally eliminates the problem of water seepage from the Z direction caused by manufacturing tolerances or aging of the glass retainer 101. At the same time, the X and Y directions are protected by sheet metal stops 302 and waterproof foam 405 to prevent the horizontal flow of residual raindrops 6, thus truly solving the problem of water ingress into the air conditioner.

[0055] The principle of the water-proof structure for an automotive air conditioning inlet provided in this embodiment of the invention is as follows:

[0056] To address the issue of rainwater entering the air conditioning inlet 301 laterally (i.e., along the Y-axis of the vehicle), the air conditioning inlet 301 is surrounded by flanges, and the bottom of the waterproof cover 4 has sealing foam. Bolts 5 are used to tighten the perimeter of the air conditioning inlet 301, creating a double-layer protective barrier that prevents raindrops from entering laterally. Simultaneously, a water-blocking rib structure is present on the side of the wiper holes 201 of the ventilation cover 2 to prevent rainwater from seeping to the back of the cover and flowing towards the air conditioning inlet 301. Similarly, a first water-blocking rib is present on the main surface of the ventilation cover 2 to intercept raindrops that seep to the back, allowing them to flow down from the rib. Meanwhile, a waterproof cover 4 is installed in the air conditioning inlet 301 area, with a ridge-like drainage channel at the top and water-blocking ribs on both sides to divert raindrops outside the waterproof cover 4. This design is unaffected by the vehicle's parking or tilting position, thus fundamentally preventing raindrops from seeping into the air conditioning inlet through the cover.
