Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a ventilation duct integrated structure used in a ceiling. Background Art
[0002] When a car is driven in different ambient temperatures, such as hot summer and cold winter, the integrated ventilation duct structure helps to evenly distribute hot and cold air to various areas in the car. For example, the cold or warm air generated by the air conditioner is delivered to the rear seating area through the ceiling ventilation duct, ensuring a uniform temperature inside the car and improving the thermal comfort of the passengers.
[0003] Existing automobile ventilation ducts are arranged in the middle space of the roof, resulting in low roof space utilization, affecting the passenger's field of vision and the space inside the car, and multiple components are scattered and fixed on the ceiling, which increases production costs. Utility Model Content
[0004] Purpose of the utility model: The purpose of the utility model is to provide a solution to the problem that the existing ventilation ducts are arranged in the middle space of the ceiling, resulting in low utilization of the ceiling space, affecting the occupant's field of vision and the space inside the vehicle, and the cost of fixing multiple components scattered on the ceiling is high.
[0005] Technical solution: A ventilation duct integrated structure used for a ceiling, comprising an integrated ceiling and a ceiling body, wherein a ventilation plate is glued and connected to the upper surface of the ceiling body.
[0006] Furthermore, the outer side wall of the ventilation plate is symmetrically and integrally formed with a ventilation duct body.
[0007] Furthermore, outer side walls of the two ventilation duct bodies are each provided with a reinforcement frame, and the two reinforcement frames are fixedly connected to the upper surface of the ceiling body.
[0008] Furthermore, the integrated roof is directly connected and installed with the roof crossbeam installation points using clips.
[0009] Furthermore, a plurality of air outlets are integrally formed on the upper surface of the ceiling body, and the plurality of air outlets are all designed to be hot-melt-welded to the ceiling body by BOSS columns.
[0010] Furthermore, the ventilation plate and the lower surfaces of the two ventilation duct bodies are integrally formed with a gluing track groove, and overflow holes are evenly distributed at an internal spacing of 30mm-50mm in the gluing track groove.
[0011] Beneficial effects:
[0012] The integrated ceiling structure can be installed in one go, reducing the number of installation stations, reducing the number of operators and assembly time, and improving production efficiency. The hot-melt welding between the air outlet and the ceiling has stable quality, and the gap-free design improves the appearance quality of the product. The ventilation duct body and the ceiling are hot-melt bonded together, avoiding the original risk of collision and abnormal noise, and also increasing the head space and field of vision in the car, improving comfort and hearing quality.

[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] like Figure 1-Figure 3 As shown, a ventilation duct integrated structure for a ceiling is provided, comprising an integrated ceiling 1 and a ceiling body 2, a ventilation plate 3 being bonded and connected to the upper surface of the ceiling body 2, and a ventilation duct body 4 being symmetrically integrally formed on the outer side wall of the ventilation plate 3;
[0020] The ventilation plate 3 and the two ventilation duct bodies 4 are all bonded to the ceiling body 2 with hot melt adhesive, avoiding the original risk of abnormal noise due to collision, increasing the head space and visual space in the car, improving comfort and auditory quality. At the same time, the integrated ceiling 1 structure is installed in one go, reducing the number of installation stations, reducing the number of operators and assembly time, and improving production efficiency.
[0021] like Figure 2 As shown, the outer side walls of the two ventilation duct bodies 4 are both provided with reinforcement frames 6, and the two reinforcement frames 6 are fixedly connected to the upper surface of the ceiling body 2;
[0022] The design of the two reinforcement frames 6 strengthens the interface strength of the two ventilation duct bodies 4, thereby increasing the service life of the device.
[0023] like Figure 1As shown, the integrated roof 1 is directly connected to the roof beam mounting point with buckles;
[0024] The integrated roof 1 is directly connected to the roof beam installation points through buckles, which can significantly improve the installation efficiency and greatly save installation time.
[0025] like Figure 2 As shown, the upper surface of the ceiling body 2 is integrally formed with a plurality of air outlets 7, and the plurality of air outlets 7 are designed to be hot-melt-welded to the BOSS column and the ceiling body 2 by hot-melt welding;
[0026] By heat-melting the multiple air outlets 7 and welding them to the ceiling body 2 through the BOSS column, it can be ensured that the multiple air outlets 7 will not be easily separated from the ceiling body 2 during long-term use even if they are affected by factors such as vehicle vibration, airflow impact and temperature changes, thereby improving the stability of the connection.
[0027] like Figure 3 As shown, the lower surfaces of the ventilation plate 3 and the two ventilation duct bodies 4 are integrally formed with a gluing track groove 5, and the internal spacing of the gluing track groove 5 is 30mm-50mm and the overflow holes 8 are evenly distributed;
[0028] The design of the glue track groove 5 of R2 facilitates glue identification and increases peeling strength. At the same time, the overflow hole 8 is set to make the glue amount more uniform in the entire glue track groove 5, thereby improving the quality and stability of the seal.
[0029] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
