Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an automobile air-conditioning air intake duct structure. Background Art

[0002] With the widespread popularity of automobiles, cars are no longer just a means of transportation, but also a mobile office and living space. With the rapid development of new energy vehicles, car buyers are more concerned about the vehicle's range. Insufficient range of electric vehicles can cause range anxiety for customers. To increase vehicle range while maintaining a certain battery capacity, the most effective way is to reduce vehicle weight. Currently, some electric vehicles on the market have eliminated the sheet metal drain trough under the front windshield of traditional gasoline vehicles. Instead, drainage is replaced by a plastic air intake duct under the ventilation cover, which is connected to the air intake of the vehicle's air conditioning box.

[0003] CN 220199015 U discloses an automotive air conditioner intake duct structure, comprising a ventilation cover and a duct housing. The duct housing includes intake ducts 1 and 2. Intake duct 2 is internally provided with a baffle and an air filter partition, respectively. The air filter partition is adjusted and deflected by a drive device to mate with the side of the baffle. A drain outlet is provided at the bottom of intake duct 1. The gas-liquid separation baffle and baffle of the automotive air conditioner intake duct are combined with an electrically adjustable air filter partition. When the air conditioner enters rainy mode and moisture is drawn into the duct, the baffle and baffle block the forward movement of water droplets, thereby preventing water from being drawn into the air conditioner. When the air conditioner enters dusty or hazy mode and is driven in dusty or hazy weather, the drive device adjusts the rotation of the air filter partition to mate with the baffle, sealing the air entering the air conditioner intake duct and purifying the air.

[0004] However, when a car is driven for a long time in dusty and foggy weather, the air filter partition will gradually be blocked by small particles in the air, resulting in poor air intake efficiency of the air duct. In addition, the air filter partition is inside the channel shell, which makes cleaning time-consuming and laborious. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the utility model provides an automobile air-conditioning intake duct structure.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an automobile air-conditioning air intake duct structure, including an air duct housing, a mounting frame movably mounted on the front and rear side walls of the air duct housing, a plurality of groups of air filter element partitions are cooperatively mounted on the mounting frame, a micro electric telescopic rod for driving the mounting frame to move is provided on the top of the air duct housing, cleaning rollers are movably mounted on the front and rear outer walls of the air duct housing, the cleaning rollers are arranged parallel to the air filter element partitions, and a micro bidirectional motor for driving the cleaning rollers to rotate is fixedly mounted on the top of the air duct housing.

[0007] Furthermore, an air inlet end is provided at the right end of the air duct housing, and a buckle is mounted on the side of the air inlet end.

[0008] Furthermore, the mounting frame is installed obliquely on the air duct housing, with the top of the mounting frame tilted toward the air inlet end. A first support seat is fixedly installed on the top inner wall of the air duct housing, and the top of the mounting frame is slidably connected to the first support seat.

[0009] Furthermore, the micro electric telescopic rod is fixedly mounted on the top of the air duct housing through a support frame, and a connecting plate is fixedly mounted on the power output end of the micro electric telescopic rod, and the connecting plate is fixedly connected to the rear end of the mounting frame.

[0010] Furthermore, the cleaning roller is located on one side of the mounting frame close to the air inlet end, a first bevel gear is fixedly mounted on the top end of the cleaning roller, a second bevel gear is fixedly mounted on the power output end of the micro bidirectional motor, and the second bevel gear is meshed with the first bevel gear.

[0011] Furthermore, a second support seat is fixedly installed on the bottom inner wall of the air duct shell, and the second support seat is located on the side of the installation frame away from the air inlet end. A baffle is hingedly installed on the top of the second support seat, and a micro stepping motor is fixedly installed on the outer wall of the air duct shell, and the power output shaft of the micro stepping motor is fixedly connected to the rotating shaft of the baffle.

[0012] Furthermore, a sealing strip is fixedly installed on one side of the top end of the baffle close to the mounting frame.

[0013] The beneficial effect of the present invention is that the design of the present invention is that a mounting frame is movably installed on the front and rear side walls of the air duct housing. After the current air filter partition has worked for a period of time, the micro electric telescopic rod drives the mounting frame to move, so that the spare air filter partition enters the interior of the air duct housing. At the same time, the micro bidirectional motor drives the cleaning roller to rotate. When the mounting frame moves, the cleaning roller quickly cleans the small particles attached to the air filter partition, thereby automatically cleaning the air filter, making it time-saving and labor-saving to clean the air filter partition, thereby avoiding clogging of the air filter partition and ensuring the air intake efficiency of the air duct when the car is driving for a long time in dusty and hazy weather.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0023] according to Figure 1-6 As shown, a car air-conditioning air intake duct structure includes an air duct housing 1, and a mounting frame 2 is movably installed on the front and rear side walls of the air duct housing 1. Several groups of air filter partitions 3 are installed on the mounting frame 2. Preferably, the number of air filter partitions 3 is two groups. A miniature electric telescopic rod 4 for driving the mounting frame 2 to move is provided on the top of the air duct housing 1, and a cleaning roller 5 is movably installed on the front and rear outer walls of the air duct housing 1. The cleaning roller 5 is arranged parallel to the air filter partition 3, and a miniature bidirectional motor 6 for driving the cleaning roller 5 to rotate is fixedly installed on the top of the air duct housing 1.

[0024] In this embodiment, an air inlet end 101 is provided at the right end of the air duct housing 1, and a buckle 102 is installed on the side of the air inlet end 101. The air inlet end 101 is connected to the ventilation cover of the car, and the air duct housing 1 and the ventilation cover are connected to each other through the buckle 102.

[0025] In this embodiment, the mounting frame 2 is installed at an angle on the air duct housing 1, and the top of the mounting frame 2 is inclined toward the direction of the air inlet end 101. A first support seat 7 is fixedly installed on the top inner wall of the air duct housing 1. The top of the mounting frame 2 is slidably connected to the first support seat 7, and the mounting frame 2 is supported by the first support seat 7 to prevent the mounting frame 2 from bending in the air duct housing 1, and to prevent air from passing through the gap between the mounting frame 2 and the top wall of the air duct housing 1.

[0026] In this embodiment, the micro electric telescopic rod 4 is fixedly mounted on the top of the air duct housing 1 through a support frame, and a connecting plate 8 is fixedly mounted on the power output end of the micro electric telescopic rod 4. The connecting plate 8 is fixedly connected to the rear end of the mounting frame 2, and the front side wall of the mounting frame 2 extends outward from the front side wall of the air duct housing 1. When the push rod of the micro electric telescopic rod 4 is pushed out, the mounting frame 2 moves toward the rear side of the air duct housing 1.

[0027] In this embodiment, the cleaning roller 5 is located on one side of the mounting frame 2 close to the air inlet end 101, and a first bevel gear 9 is fixedly installed on the top of the cleaning roller 5. A second bevel gear 10 is fixedly installed on the power output end of the micro bidirectional motor 6. The second bevel gear 10 is engaged with the first bevel gear 9. When the micro electric telescopic rod 4 is started, the micro bidirectional motor 6 drives the second bevel gear 10 to rotate, and the cleaning roller 5 is rotated under the cooperation of the second bevel gear 10 and the first bevel gear 9, so that the cleaning roller 5 is used to clean the small particles attached to the air filter element partition 3.

[0028] In this embodiment, a second support seat 11 is fixedly installed on the bottom inner wall of the air duct housing 1, and the second support seat 11 is located on the side of the mounting frame 2 away from the air inlet end 101. A baffle 12 is hingedly installed on the top of the second support seat 11, and a sealing strip 14 is fixedly installed on the top of the baffle 12 close to the side of the mounting frame 2. A micro stepping motor 13 is fixedly installed on the outer wall of the air duct housing 1, and the power output shaft of the micro stepping motor 13 is fixedly connected to the rotating shaft of the baffle 12. When the air conditioner enters the dust and haze mode, the micro stepping motor 13 drives the baffle 12 to rotate toward the mounting frame 2, and the baffle 12 is tightly attached to the bottom end of the mounting frame 2, so that the air passes through the air filter partition 3 and enters the interior of the car, thereby achieving the purpose of purifying the air.

[0029] When the utility model is in use, one group of air filter partitions 3 is located inside the air duct housing 1 to purify the air, and the other group of air filter partitions 3 is located outside the air duct housing 1 for standby. After the current air filter partition 3 has worked for a period of time, the micro electric telescopic rod 4 drives the installation frame to move, so that the spare air filter partition 3 enters the interior of the air duct housing, and at the same time, the micro bidirectional motor 6 drives the cleaning roller 5 to rotate. When the installation frame 2 drives the air filter partition 3 to pass through the cleaning roller 5, the cleaning roller 5 quickly cleans the small particles attached to the air filter partition 3, thereby automatically cleaning the air filter 3, making it time-saving and labor-saving to clean the air filter partition 3, thereby avoiding clogging of the air filter partition 3, and ensuring the air intake efficiency of the air duct when the car is driving for a long time in dusty and hazy weather.

[0030] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
