[0002] Most of the defrosting air ducts of passenger cars on the market at present are integrally formed. With the continuous improvement of the public's needs and styling styles, the space in the front part of the cockpit of some vehicle models is very wide, and the instrument panel has a long dimension in the front-back longitudinal direction. The instrument panel cannot enter the door frame integrally and needs to be disassembled at the front end part of the instrument panel to enter the door frame. The corresponding defrosting air duct to the instrument panel also cannot enter the vehicle body integrally and needs to be disassembled. And how to disassemble the defrosting air duct to facilitate the accurate installation and combination of the defrosting air duct is a problem that must be considered. Content of the Utility Model
[0003] Aiming at the defects of the above-mentioned prior art, the utility model provides a defrosting air duct with simple connection, which solves the problem of how to conveniently and accurately assemble and install the defrosting air duct in a relatively limited vehicle body space. The utility model also provides an instrument panel assembly and a vehicle with the defrosting air duct with simple connection.
[0004] The technical solution of the utility model is as follows: A defrosting air duct with simple connection, including a front defrosting air duct, a connecting air duct, a rear defrosting air duct, a front cover plate and a rear cover plate.

The rear cover plate covers the top surface of the rear defrosting air duct and closes the top opening. The rear port of the front defrosting air duct is connected to the front port of the connecting air duct, and the rear port of the connecting air duct is connected to the front port of the rear defrosting air duct. The front port of the connecting air duct is inclined in the front-upper direction.
[0005] Further, in order to make the position of the front defrosting air duct and the connecting air duct relatively more convenient, the rear port of the front defrosting air duct and the front port of the connecting air duct are set as mutually matching bevels.
[0006] Further, in order to make the position of the rear defrosting air duct and the connecting air duct relatively more convenient, at least one of the rear port of the connecting air duct and the front port of the rear defrosting air duct is provided with a guiding socket for inserting the rear port of the connecting air duct and / or the front port of the rear defrosting air duct.
[0007] Further, in order to reduce air leakage between the connections of the various components of the defrosting air duct, sealing cotton is provided between the rear port of the front defrosting air duct and the front port of the connecting air duct, and between the rear port of the connecting air duct and the front port of the rear defrosting air duct.
[0008] Further, the front defrost air duct and the rear defrost air duct are provided with a plurality of air guiding ends, and defrost grilles are provided at corresponding positions of the front cover plate and the rear cover plate where the air guiding ends are located.

[0022] The following further illustrates the present utility model in conjunction with embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. After reading this description, various equivalent forms of modification of this description by those skilled in the art all fall within the scope defined by the appended claims of this application.
[0023] The vehicle involved in this embodiment includes an instrument panel assembly. The instrument panel assembly includes an appearance covering part and a skeleton, and also includes a defrosting air duct with a simple connection. Please combine Figures 1 to 7 As shown, the defrosting air duct with a simple connection mainly includes a front defrosting air duct 1, a connecting air duct 2, a rear defrosting air duct 3, a front cover plate 4 and a rear cover plate 5.
[0024] The rear defrosting air duct 3 has a structure with an open top. The top of the rear defrosting air duct 3 is covered by the rear cover plate 5 to form a ventilation duct. The air inlet 301 of the rear defrosting air duct 3 is located at the bottom surface in the middle thereof. The air inlet 301 is matched with the air outlet of the air conditioner to introduce the air output from the air conditioner into the defrosting air duct. The front port 302 of the rear defrosting air duct 3 is an interface for connecting with the connecting air duct 2. The rear defrosting air duct 3 extends to the left and right sides in the middle to form an air flow channel, and the end section of the air flow channel is a wind guiding end 303. A defrosting grille 6 is arranged at the position of the wind guiding end 303 on the rear cover plate 5. After the air flow reaches the wind guiding end 303, it blows out from the defrosting grille 6 and is guided by the defrosting grille 6. As a preferred embodiment, in this embodiment, an inclined section is made at the wind guiding end 303 of the rear defrosting air duct 3, that is, the bottom of the wind guiding end 303 of the rear defrosting air duct 3 is gradually raised towards the end of the wind guiding end 303, and the air flow cross-section gradually decreases towards the end of the wind guiding end 303 of the rear defrosting air duct 3. In this way, the air can be better guided to the left and right defrosting grilles 6 without causing a sudden change in air volume and pressure.
[0025] The connecting air duct 2 is a pipe that is open in the front and rear directions. The rear port 202 of the connecting air duct 2 is inserted into the front port 302 of the rear defrosting air duct 3, and the front port 201 of the connecting air duct 2 is connected to the rear port 101 of the front defrosting air duct 1. Among them, the rear port 202 of the connecting air duct 2 is arranged in the vertical direction, the front port 201 of the connecting air duct 2 is arranged in an inclined direction facing the front upper direction, and both sides of the connecting air duct 2 are provided with a plurality of connecting feet 203 for connecting to the vehicle body. After the rear defrosting air duct 3 is installed and fixed on the connecting air duct 2, since there is a relatively large remaining space (the rear end of the connecting air duct 2 is the end far from the windshield), the rear port arranged in the vertical direction also facilitates the adjustment of the position of the rear defrosting air duct 3 for connection and installation. And for the front port 201 of the inclined connecting air duct 2, when installing the front defrosting air duct 1, it can be docked with the connecting air duct 2 in a tilting movement manner. The front defrosting air duct 1 can be assembled with the connecting air duct 2 after the connecting air duct 2 is fixed, without first combining the two, which is convenient for operation.
[0026] As a preferred embodiment, in this embodiment, the front port 302 of the rear defrosting air duct 3 is provided with a guiding socket 304, and the outer diameter of the guiding socket 304 matches the inner diameter of the rear port 202 of the connecting air duct 2. In this way, when connecting the rear defrosting air duct 3 and the connecting air duct 2, it is easy to align the two, thereby improving the installation efficiency. In addition, it should be noted that the guiding socket 304 can also be arranged at the rear port 202 of the connecting air duct 2. During installation, the guiding socket 304 is correspondingly inserted into the front port 302 of the rear defrosting air duct 3. At the same time, the rear port 101 of the front defrosting air duct 1 and the front port 201 of the connecting air duct 2 are set as mutually matching bevels. During installation, the accurate relative position of the front defrosting air duct 1 and the connecting air duct 2 can be easily confirmed through the matching of the bevel angles.
[0027] In order to reduce air leakage at the connection positions of the front defrosting air duct 1, the rear defrosting air duct 3 and the connecting air duct 2, a ring of sealing cotton 7 is arranged between the rear port 202 of the connecting air duct 2 and the front port 302 of the rear defrosting air duct 3, and between the front port 201 of the connecting air duct 2 and the rear port 101 of the front defrosting air duct 1. During connection and installation, the sealing cotton 7 can fill the assembly gap between the front defrosting air duct 1, the rear defrosting air duct 3 and the connecting air duct 2 to ensure sealing.
[0028] The structure of the front defrost air duct 1 is similar to that of the rear defrost air duct 3, and it is also a structure with an open top. The top of the front defrost air duct 1 is covered by a front cover plate 4 to form a ventilation duct. The rear port 101 of the front defrost air duct 1 is the air inlet 301. The front defrost air duct 1 extends to the left and right sides in the middle to form an air flow channel, and the end section of the air flow channel is the air guiding end 102. A defrosting grille 6 is arranged at the position of the air guiding end 102 on the front cover plate 4. After the air flow reaches the air guiding end 102, it blows out from the defrosting grille 6 and is guided by the defrosting grille 6. As a preferred embodiment, in this embodiment, an inclined section is made at the air guiding end 102 of the front defrost air duct 1, that is, the bottom of the air guiding end 102 of the front defrost air duct 1 is gradually raised towards the end of the air guiding end 102, and the air flow cross-section gradually decreases towards the end of the air guiding end 102 of the front defrost air duct 1. In this way, the air can be better guided to the left and right defrosting grilles 6 without causing a sudden change in air volume and pressure.
[0029] As a preferred embodiment, in this embodiment, a wind guiding partition 8 is arranged in the simply-connected defrost air duct to distribute the incoming air volume of the air conditioner flowing to each position. Specifically, there are two segmented and spliced wind guiding partitions 8, that is, the wind guiding partition 8 has a part in the front defrost air duct 1 and the connecting air duct 2 respectively. After the two are connected, these parts are spliced to form a wind guiding partition 8 extending in the front-rear direction. The wind guiding partition 8 is connected to the bottoms of the front defrost air duct 1 and the connecting air duct 2. A partition 9 for partitioning the incoming air at the air inlet 301 is also arranged at the position of the air inlet 301 of the rear defrost air duct 3. In this way, after entering the simply-connected defrost air duct from the air outlet of the air conditioner, under the blocking effect of the partition 9, the air can smoothly flow to the air guiding ends 303 on both sides of the rear defrost air duct 3 and flow to the connecting air duct 2. The air flow in the connecting air duct 2 is further guided by the wind guiding partition 8 to evenly flow into the front defrost air duct 1, and then better guide the air to the edge area of the front windshield.
[0030] The installation process of the simply-connected defrost air duct is as follows:
[0031] 1. The rear cover plate 5 and the rear defrost air duct 3 are combined by various processes, such as welding and screw fastening; after that, the left and right defrosting grilles 6 on the rear cover plate 5 are installed; a sealing cotton 7 is pasted on the front port 302 of the rear defrost air duct 3;
