Abstract
Description
Technical Field
[0001] This utility model relates to an integrated device for vehicle air conditioning return air grille and air duct top profile, which can be applied to air duct luggage racks in new energy / traditional buses / trucks. Background Technology
[0002] Air conditioning return air grille: A separate air conditioning return air grille installed on the interior headliner creates a sense of discontinuity in the headliner, affecting the aesthetics of the interior. At the same time, a separate return air grille increases the overall weight and cost of the vehicle. Utility Model Content
[0003] The technical problem to be solved by this utility model is: how to solve the sense of discontinuity in the interior roof panel of a bus, and further reduce the weight and cost of the whole vehicle, by providing an integrated device for the air return grille and the top profile of the air duct for vehicle air conditioning.
[0004] To solve the above problems, this utility model is achieved through the following technical solution:
[0005] An integrated device for a vehicle air conditioning return air grille and duct top profile includes a duct top profile, wherein the duct top profile includes an aluminum profile body, and a return air grille opening is provided on the aluminum profile body, the position of the return air grille opening facing the air conditioning evaporator.
[0006] The aluminum profile body is connected to the hanger via a second bolt.
[0007] The aluminum profile body is an extruded aluminum profile.
[0008] The aluminum profile body has a slot, and an ambient light is installed in the slot; and a flange is provided at the end of the aluminum profile body to cover the ambient light.
[0009] An installation plate extends from the side of the aluminum profile body. The installation plate is provided with fine threaded grooves. Bolts are connected to the fine threaded grooves. The installation plate is used to connect the air duct baffle to the aluminum profile body via bolts.
[0010] Compared with the prior art, the present invention has the following beneficial effects: the air conditioning return air grille of the vehicle is integrated with the air duct top profile, the air duct top profile is an extruded aluminum profile, the integrated air conditioning return air grille adopts a hidden structure, which improves the aesthetics and achieves weight reduction and cost reduction; at the same time, the aluminum profile integrates the ambient light installation structure, and the hidden ambient light is achieved by adjusting the illumination angle, which improves the aesthetics.

[0011] Figure 1 This is an overall structural diagram of the present invention;
[0012] Figure 2 This is a diagram of the end structure of this utility model;
[0013] Figure 3 This is a structural diagram of the installation state of this utility model. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] like Figure 1 , Figure 2 As shown, an integrated device for a vehicle air conditioning return air grille and duct top profile includes a duct top profile 1. The duct top profile 1 includes an aluminum profile body 11, on which a return air grille opening 13 is provided. The return air grille opening 13 is positioned facing the air conditioning evaporator. At the same time, a filter screen is added inside the air conditioning evaporator. In this way, the present invention integrates the return air grille and the duct top profile 1 to achieve weight reduction and cost reduction.
[0017] Furthermore, the aluminum profile body 11 is an extruded aluminum profile, integrating an air conditioning return air grille, and adopting a hidden structure to improve aesthetics and achieve weight reduction and cost reduction.
[0018] Furthermore, the aluminum profile body 11 is provided with a slot 12, and an ambient light 14 is installed in the slot 12; and a flange 15 is provided at the end of the aluminum profile body 11, which covers the ambient light 14, thus hiding the ambient light 14 and improving aesthetics. It should be noted that after assembly, the ambient light 14 needs to be adjusted in terms of illumination angle.
[0019] Furthermore, an installation plate 17 extends from the side of the aluminum profile body 11. The installation plate 17 is provided with a fine threaded groove 18. Bolts are connected to the fine threaded groove 18. The installation plate 17 is used to connect the air duct baffle 16 to the aluminum profile body 11 via bolts. In this way, the design of the fine threaded groove 18 can prevent the bolts from stripping after disassembly.
[0020] Furthermore, the aluminum profile body 11 is connected to the hanger 2 by the second bolt 19, thereby installing the air duct top profile 1 on the hanger 2, and the luggage rack end baffle 3 is connected below the hanger 2.
[0021] The principle of this utility model is:
[0022] 1. The air duct top profile integrates the air conditioner return air grille, improving aesthetics and reducing costs and weight;
[0023] 2. Eliminate the original traditional fixed profile of the air duct to solve the problem of profile deformation under load: Use an integrated bracket to fix the air duct to the bracket, and fix the top profile of the air duct to the bracket. It only serves a decorative purpose, does not bear weight, and has no deformation problem.
[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
