Description

Technical Field

[0001] The utility model relates to the problem of waterproofing of a vehicle air conditioner in rainy days. Background Art

[0002] On rainy days, to ensure forward visibility and defog the windshield, drivers often switch the air conditioner to external circulation mode and set the air supply to maximum. However, research into the waterproofness of the air conditioner vents on the dash panel revealed that, in this situation, water dripping from the windshield and A-pillars can fall in front of the air conditioner intake. Due to the air conditioner's powerful suction force (mostly occurring when the air conditioner is at maximum speed), water can easily be sucked into the vents, causing issues with the air conditioner's watertightness.

[0003] Existing patent CN219780414U relates to functional components for drying automotive air conditioning filters and the overall system operation control logic. This patent, which describes a device for drying air conditioning filters, has nothing to do with the waterproofing of the air conditioning inlet. In other words, the technical solution in CN219780414U fails to effectively prevent the fundamental problem of water ingress into the air conditioning inlet, and in fact lacks any waterproofing capability.

[0004] The information disclosed in the background section of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0117] It should be understood that the accompanying drawings are not necessarily drawn to scale, and that they illustrate various features of the basic principles of the present invention in a somewhat simplified manner. The specific design features of the present invention disclosed herein, including, for example, specific dimensions, orientations, positioning, and shapes, will be determined in part by the specific intended application and use environment.

[0118] In the drawings, reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the drawing. DETAILED DESCRIPTION

[0119] Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. The exemplary embodiment is an example and can be implemented in various forms by those skilled in the art. Therefore, the present invention is not limited to the exemplary embodiment described herein.

[0120] Figure 1A The installation diagram of the air conditioning air inlet waterproof device 100 at the front panel of the vehicle according to the present invention is shown. As shown in FIG1 , the air conditioning air inlet waterproof device 100 at the front panel of the vehicle is installed at the air conditioning air inlet of the front panel 200 of the vehicle.

[0121] Figure 1B A schematic diagram of a waterproof device for an air-conditioning air inlet at a vehicle's front panel is shown.

[0122] Figure 2 A three-dimensional exploded view of the air conditioning air inlet waterproof device at the front panel of a vehicle according to the present invention is shown.

[0123] like Figure 2 As shown, the vehicle dash panel air inlet waterproofing device 100 of the present invention includes a main frame A, a first water deflector B, a first slide rail assembly B-1, a second water deflector C, a second slide rail assembly C-1, a motor D, a motor mounting cover D-1, a sealing strip E, fasteners H-1 (e.g., screws and nuts), and fixing bolts H-2. The vehicle dash panel air inlet waterproofing device 100 is controlled by a main controller HU. The main controller HU can be a microprocessor or any suitable programmable controller.

[0124] The main body frame A is used to fix the air-conditioning air inlet waterproof device 100 at the vehicle's front panel to the air-conditioning air inlet at the vehicle's front panel.

[0125] The assembly order of the first water baffle B, the first slide rail assembly B-1, the second water baffle C, and the second slide rail assembly C-1 is as follows: first, insert the first water baffle B and the second water baffle C from the left and right sides of the main frame A respectively, then insert the first slide rail assembly B-1 and the second slide rail assembly C-1 from the left and right sides of the main frame A respectively and snap them onto the main frame A, as shown in the figure. Figure 3 shown.

[0126] Figure 4 The first slide rail assembly B-1 and its partial enlarged view are shown. Figure 4 As shown, the first slide rail assembly B-1 has two first guide posts B-1-a extending horizontally to the right, and two upper and lower first hooks B-1-b extending horizontally to the right. The enlarged view shows the structural details of one of the first hooks B-1-b.

[0127] Figure 5 The second rail assembly C-1 is shown. Figure 5 As shown, the second rail assembly C-1 has a second guide column C-1-a extending horizontally to the left. Similar to the first rail assembly B-1, the second rail assembly C-1 also has two second hooks C-1-b, which extend horizontally to the left (see below). Figure 6 (large image of partial release in [4].

[0128] Figure 6 Shown is a stereoscopic view and a partially enlarged view of the waterproof device for the air-conditioning air inlet at the front panel of a vehicle according to the present invention.

[0129] Figure 6 The partial image in the figure shows the second hook C-1-b of the second rail assembly C-1 engaging with the engagement hole Ab on the right side of the main frame A. Although not shown, the first hook B-1-b of the first rail assembly B-1 also engages with the engagement hole Ab on the left side of the main frame A. Thus, the first and second rail assemblies B-1 and C-1 are assembled with the main frame A.

[0130] The number of the first hook B-1-b and the second hook C-1-b is two, so as to be fixed at the upper and lower ends of the body frame A. Of course, the number of the first hook B-1-b and the second hook C-1-b is more than two, in order to provide a more secure fixation.

[0131] The fixed state in which the first hook B-1-b and the second hook C-1-b are engaged with the engaging hole Ab is only an example. Any method of assembling the first rail assembly B-1 and the second rail assembly C-1 with the main frame A is possible, for example, by screw connection.

[0132] The second slide rail assembly C-1 has a second positioning hole C-1-c. Figure 6 The partial large picture in the figure shows the state in which the first guide column B-1-a is about to be inserted into the positioning hole C-1-c of the second slide rail assembly C-1. Figure 6 The partially enlarged image is intended to illustrate the assembly process. When the air conditioning inlet waterproofing device on the vehicle's dash panel is fully assembled, the first guide post B-1-a is already inserted into the locating hole of the second rail assembly C-1. Although not shown, the first rail assembly B-1 has a first locating hole. The second guide post C-1-a also inserts into the locating hole of the first rail assembly B-1. This ensures that the free ends of the first and second guide posts B-1-a are securely positioned.

[0133] The first guide post B-1-a is inserted into the positioning hole C-1-c of the second rail assembly C-1, and the second guide post C-1-a is inserted into the positioning hole of the first rail assembly B-1. This provides support for the first and second guide posts B-1-a and C-1-a, preventing a cantilevered state and improving rigidity. Of course, the positioning holes can also be slots, as long as they provide support. If the first and second guide posts B-1-a and C-1-a are sufficiently rigid, a cantilevered state can be achieved without this support.

[0134] Figure 7 Shows a perspective view of the first water retaining plate B. Figure 7 As shown, the first water baffle B includes a first baffle portion Ba capable of shielding the left half of the air inlet of the main body frame A, a first upper side bar B-b1 extending horizontally to the right from the top of the first baffle portion Ba, and a first lower side bar B-b2 extending horizontally to the right from the bottom of the first baffle portion Ba. As a result, a space open to the right is formed between the first baffle portion Ba, the first upper side bar B-b1, and the first lower side bar B-b2.

[0135] Figure 8 Shows a perspective view of the second water retaining plate C. Figure 8As shown, the second water baffle C includes a second baffle portion Ca capable of shielding the right half of the air inlet of the main body frame A, a second upper side bar C-b1 extending horizontally to the left from the top of the second baffle portion Ca, and a second lower side bar C-b2 extending horizontally to the left from the bottom of the second baffle portion Ca. Thus, a space open to the left is formed between the second baffle portion Ca, the second upper side bar C-b1, and the second lower side bar C-b2.

[0136] Figure 9 It is a perspective view showing a waterproof device 100 for an air-conditioning air inlet at a front panel of a vehicle according to the present invention.

[0137] Figure 10 Shows along Figure 9 The cross-sectional view is obtained by cutting the line aa in FIG. Figure 10 As shown, the first upper side bar B-b1 of the first water retaining plate B is embedded in the upper fitting groove A-a1 of the main body frame A, and the first lower side bar B-b2 is embedded in the lower fitting groove A-a2 of the main body frame A. Figure 10 It is shown that the first water baffle B has a first upper guide hole B-d1 and a first lower guide hole B-d2 running through the left and right sides. The first upper guide hole B-d1 and the first lower guide hole B-d2 extend along the first upper side bar B-b1 and the first lower side bar B-b2 respectively; the two first guide columns B-1-a slideably cooperate with the first upper guide hole B-d1 and the first lower guide hole B-d2 respectively. Figure 10 It is also shown that there is a gap between the first upper side bar B-b1 and the upper fitting groove A-a1, and there is a gap between the first lower side bar B-b2 and the lower fitting groove A-a2.

[0138] Figure 11 Shows along Figure 9 The cross-sectional view is obtained by cutting the bb line in the figure. Figure 11 As shown, the second upper side bar C-b1 of the second water retaining plate C is embedded in the upper fitting groove A-a1 of the main body frame A, and the second lower side bar C-b2 is embedded in the lower fitting groove A-a2 of the main body frame A. Figure 11 It is shown that the second water retaining plate C has a second upper guide hole Ce running through from left to right, and the second upper guide hole Ce extends along the second upper side bar C-b1; the second guide column C-1-a is in sliding fit with the second upper guide hole Ce. Figure 11 It is also shown that there is a gap between the second upper side bar C-b1 and the upper fitting groove A-a1, and there is a gap between the second lower side bar C-b2 and the lower fitting groove A-a2.

[0139] Combine Figure 10 、 Figure 11It can also be seen that the cross-section of the second lower edge strip C-b2 is roughly L-shaped, with the height of its vertical side roughly equal to the lower fitting groove A-a2, and the dimension of its horizontal side Cc roughly equal to the width of the lower fitting groove A-a2. The second water retaining plate C is located in front of the first water retaining plate B. This is merely an example; the second water retaining plate C can also be located behind the first water retaining plate B, as long as the second water retaining plate C and the first water retaining plate B can slide freely left and right.

[0140] The structure in which the first water baffle B and the second water baffle C are embedded in the upper fitting groove A-a1 and the lower fitting groove A-a2 of the main body frame A is intended to shield the sliding structure of the first water baffle B and the second water baffle C, thereby making the structure of the entire device more complete. Of course, even if the main body frame A does not have the upper fitting groove A-a1 and the lower fitting groove A-a2, it will not affect the sliding of the first water baffle B and the second water baffle C along the first guide column B-1-a and the second guide column C-1-a, respectively.

[0141] Figure 12 The driving mechanism of the waterproof device for the air-conditioning air inlet at the front panel of the vehicle of the present invention is shown, and the enlarged view thereof shows the detailed structure of the driving mechanism. Figure 12 As shown, the drive mechanism includes a first rack Bc fixedly mounted to the lower surface of the first lower side bar B-b2, a second rack Cd fixedly mounted to the upper surface of the horizontal side Cc of the second lower side bar C-b2, and a drive mechanism D. The drive mechanism D includes a motor Da and a gear Db driven by the motor Da. The gear Db meshes with the first rack Bc and the second rack Cd simultaneously. This drives the first water baffle B and the second water baffle C to move toward or away from each other.

[0142] In the above example, the first rack Bc and the second rack Cd are separate parts. Alternatively, the first rack Bc may be integrally formed on the lower surface of the first lower side bar B-b2, and the second rack Cd may be formed on the upper surface of the transverse side Cc of the second lower side bar C-b2.

[0143] Figure 13 FIG. 1 shows an example of the installation structure of the drive mechanism D, wherein an enlarged view shows the installation details. Figure 13 As shown, the motor Da of the drive mechanism D is fixed to the body frame A via a motor fixing cover D-1 and fixing bolts H-2. It should be noted that this mounting structure is only for illustrative purposes, and any structure capable of mounting the drive mechanism D to the body frame A is permitted.

[0144] Figure 14 FIG. 4 shows an example of a cable fixing structure of a drive mechanism D. Figure 14As shown, the drive mechanism D has a cable Dc, and the body frame A has a wire clamp structure Ac and a wire routing hole Ad, through which the cable Dc is fixed. This wire clamp structure and routing hole fixing structure are only examples, and any structure capable of fixing the cable is acceptable.

[0145] Figure 15 The figure shows the installation structure of the waterproof device for the air-conditioning air inlet at the front panel of the vehicle. Figure 15 As shown, the body frame A is secured to the dash panel via fasteners H-1. A sealing strip E is installed between the perimeter of the body frame A and the dash panel to prevent water from entering through the gap between the dash panel's air conditioning inlet and the body frame A. Of course, the sealing strip E is optional; the body frame A's inherent sealing structure is sufficient to ensure a seal with the dash panel.

[0146] Figure 16 Shows along Figure 15 The cross-sectional view obtained by cutting the mid-cc line. Figure 16 As shown, a sealing groove is provided around the window of the body frame A, and the sealing strip E is embedded in the sealing groove, thereby setting the sealing strip E between the body frame A and the air conditioning air inlet at the vehicle front panel 200. Of course, the sealing groove can also be provided on the front panel.

[0147] Figure 17 Shows along Figure 15 The cross-sectional view obtained by cutting the mid-dd line. Figure 17 As shown, bolts are fixedly installed (for example, by welding) around the air-conditioning air inlet at the front panel of the vehicle 200. The bolts pass through the mounting holes on the main body frame A. The waterproof device 100 for the air-conditioning air inlet at the front panel of the vehicle is fixed to the air-conditioning air inlet at the front panel of the vehicle 200 through the cooperation of the nut (fastener) H-1 and the bolt.

[0148] Figure 18 A front view of the vehicle dash panel air conditioning air inlet waterproof device of the present invention is shown, with a partial enlarged view showing a drain outlet provided on one side of the main body frame A. This drain outlet Ae is a groove structure. When the main body frame A is mounted on the vehicle dash panel air conditioning air inlet 200, the drain outlet Ae connects the interior and exterior of the vehicle dash panel air conditioning air inlet waterproof device.

[0149] Figure 19 Shows along Figure 18 The cross-sectional view obtained by cutting the ee line. Figure 19As shown, a guide groove Af is formed around the air inlet on the inner side of the body frame A. Water entering the interior of the air conditioning air inlet waterproof device at the front panel of the vehicle will flow into the guide groove Af along the inner wall and eventually flow downward along the inner wall.

[0150] Figure 19 The figure also shows a gap between the first water baffle B and the second water baffle C, which forms an L-direction air inlet. When both the first water baffle B and the second water baffle C are moved to the center, the air flow from the front in the T direction is blocked, thereby blocking the falling rainwater; however, air can still enter the air conditioner through the L-direction air inlet.

[0151] Figure 20 The figure shows the inner side view of the waterproof device for the air-conditioning air inlet at the front panel of the vehicle of the present invention. The inner side of the main body frame A has a bottom wall Ag inclined toward the drain outlet Ae. Figure 20 As shown by the dotted arrow in , the water flowing down the inner wall of the main body frame A will eventually reach the bottom wall Ag and then flow out of the drain port Ae along the bottom wall Ag.

[0152] Figure 21A 、 Figure 21B 、 Figure 21C and Figure 21D The figure shows the position changes of the first water baffle B and the second water baffle C during the activation of the waterproof mode of the air conditioning air inlet waterproof device at the front panel of the vehicle.

[0153] On rainy days, in order to ensure the front view and remove the fog from the front windshield, the driver usually adjusts the air conditioner blowing mode to external circulation and adjusts the air supply gear to the maximum gear, such as Figure 21A In this case, when the rainfall is too heavy and the water falling from the upper end is sucked into the air-conditioning intake, the device starts the waterproof mode (i.e., the first water baffle B and the second water baffle C move toward the center → in the T direction (the front and rear direction of the vehicle, see Figure 1A As shown in the figure, the air inlet of the air conditioner is blocked to prevent water from entering the air conditioner port, while the air sucked in by the air conditioner enters from both ends of the device and is sucked into the air conditioner port. Figure 21B The arrows in the figure show that the first water baffle B and the second water baffle C move from the air supply gear to the maximum gear toward the center. Figure 21C The first water baffle B and the second water baffle C are shown to move to the middle, blocking the air conditioning air inlet in the T direction; at this time, both ends of the first water baffle B and the second water baffle C still have smaller air inlets in the L direction to allow air to enter, as shown in FIG. Figure 21D Please note that Figure 21C 、 Figure 21D It is the same state, but at different observation angles, where Figure 21DIn the figure, we can see the L-direction air inlet at the end of the second water baffle C. It should be noted that the end of the first water baffle B also has an L-direction air inlet (not shown).

[0154] Figure 22 The working process of the waterproof device for the air-conditioning air inlet at the front panel of a vehicle of the present invention is described.

[0155] like Figure 22 As shown, when the engine is in working state, step S1 is started, the main controller HU reports continuously, and in step S2 it is determined whether there will be heavy rain within 30 minutes.

[0156] Once it is determined that there will be heavy rain within 30 minutes, a pop-up window prompt will be displayed through the main controller display screen (HU display screen) in step S3, and the driver will be asked whether to automatically start the air conditioning waterproof mode.

[0157] If the driver chooses to press the "Start Now" screen button, it proceeds to step A1; if the driver chooses to press the "Cancel" screen button, it proceeds to step B1.

[0158] Following step A1, the process proceeds to step A2. In step A2, if the precipitation is at least 10 mm (as measured by the rain sensor), the air conditioning airflow is at maximum, and the air conditioning is in external circulation mode, the process proceeds to step B5. In step B5, the waterproof mode is activated.

[0159] Following step B5, in step B6, it is determined whether the following conditions are met simultaneously:

[0160] 1. Is the air supply volume of the air conditioner less than the maximum (MAX) air supply volume?

[0161] 2. Is the air conditioning air supply external circulation mode changed or turned off?

[0162] If the conditions in B6 are not met at the same time (ie the air conditioner is still in the maximum air volume and external circulation mode), then go to step B9, that is, the waterproof mode remains on.

[0163] If the condition in B6 is met (i.e., the air volume of the air conditioner is less than the maximum air volume, or it is no longer in external circulation air supply mode), the process proceeds to step B7, where the waterproof mode is turned off, restoring the state before entering the waterproof mode. Then, step B8 is skipped and the HU display prompts "Waterproof Mode Off."

[0164] After step B1, the system proceeds to step B2. If the precipitation is at least 10 mm (as measured by the rain sensor), the air conditioning airflow is at maximum, and the air conditioner is in external circulation mode, the system proceeds to step B3. In step B3, the driver is prompted as follows: 1. A pop-up window appears on the HU display: "Air conditioning waterproof mode automatically activated." 2. The steering wheel vibrates.

[0165] Next, if the driver chooses to press the "Start Now" screen button, the process proceeds to step B4; if the driver chooses to press the "Cancel" screen button, the process proceeds to step B10.

[0166] Following step B10 , the process proceeds to step B11 , where the waterproof device for the air-conditioning air inlet at the front panel of the vehicle maintains the current working state until the engine is shut down.

[0167] Following step B4, the process proceeds to step B5 to activate the waterproof mode. The subsequent steps B6, B7, B8, and B9 are the same as previously described.

[0168] Figure 23 This is a modified example of the waterproof device for the air conditioning air inlet at the front panel of the vehicle in this experimental device. Figure 24 To follow Figure 23 The cross-sectional view is obtained by taking the line ff in FIG.

[0169] like Figure 23 As shown, compared to previous embodiments, this deformation force is now enhanced by a forward extension plate Ah on the upper portion of the main frame A. This plate is slightly angled forward and downward, preventing rainwater from flowing through the junction of the front windshield G and the front panel F toward the air conditioning intake. It also directs any falling water toward the front and downward, thus further preventing problems caused by rainwater entering the air conditioning intake. The forward extension plate Ah is fixedly mounted to the upper end of the main frame A and extends forward. Of course, the forward extension plate Ah can also be integrally formed with the main frame A.

[0170] Figure 24 Schematic diagram of the body frame A with the front extension plate Ah installed at the front of the vehicle. Figure 24 As shown, rainwater drips onto the front extension plate Ah through the front windshield G and the front panel 200, flows forward along the front extension plate Ah, and drips downward in front of the main body frame A, thereby avoiding entering the opening of the main body frame A and entering the air conditioning port.

[0171] Through the structure of the above-mentioned technical solution of the utility model, the waterproof device for the air conditioning air inlet on the front panel of the experimental device improves the safe use conditions of the vehicle air conditioning. It allows the air conditioning external circulation mode to remove fog from the front windshield during heavy rain, and at the same time prevents water sliding down the front windshield and A-pillar from being sucked into the air conditioning vent. The technical solution of the utility model can also prevent water sprayed by the high-pressure water gun during high-pressure car washing from entering the air conditioner through the air conditioning air inlet on the front panel.
