Description

Technical Field

[0001] The utility model belongs to the field of automobile air conditioning and relates to a centrally mounted double laminar flow blower assembly structure and an automobile air conditioning system. Background Art

[0002] In the evolution of automotive air conditioning systems, blowers are one of the core components, and the convenience of their installation and removal has always been the focus of engineers. However, the traditional design of automotive air conditioning blowers often has technical pain points such as inconvenient installation and removal, which to a certain extent limits the overall performance improvement of automotive air conditioning systems and the efficiency of after-sales service.

[0003] First, the traditional blower design is usually located in a relatively hidden position in the car air conditioning system, such as under the dashboard or in the engine compartment. This means that when the blower fails or needs maintenance, technicians often need to remove multiple parts to reach the blower itself. This complicated disassembly process is not only time-consuming and labor-intensive, but also easy to damage other parts during the disassembly process, increasing the cost and difficulty of maintenance.

[0004] Secondly, the structural design of traditional blowers is often complex, including multiple fasteners, seals and connectors. These complex structures need to be precisely aligned and fastened during installation. Improper installation may cause the blower to run unstably, make loud noises or even fail to work. This installation difficulty not only increases manufacturing costs, but also brings great challenges to after-sales service. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a centrally mounted double laminar flow blower assembly structure and an automobile air conditioning system, so as to improve the convenience of installation and disassembly of the automobile air conditioning blower.

[0006] In order to achieve the above object, the utility model provides the following technical solutions:

[0007] A centrally mounted double laminar flow blower assembly structure comprises an air conditioning box body having a double laminar flow structure and a flange connection component, wherein the flange connection component is installed on the air conditioning box body through a centering positioning device to ensure the center position of the flange connection component.

[0008] Optionally, the centering positioning device includes at least one positioning pin and a corresponding positioning hole, the positioning pin is arranged on the air-conditioning box body, and the positioning hole is arranged on the flange connecting component, and the centering installation of the flange connecting component is achieved through the cooperation between the positioning pin and the positioning hole.

[0009] Optionally, the flange connection component is an annular structure, with a connection interface matching the air outlet of the air conditioning box body provided inside, and a connection flange connected to an external pipeline or equipment provided on the outside of the flange connection component.

[0010] Optionally, the air conditioning box body and the flange connection component are connected via a threaded structure, and a self-tapping screw passes through a mounting hole on the air conditioning box body to fix the flange connection component to the air conditioning box body.

[0011] Optionally, a sealing gasket is provided between the air conditioning box body and the flange connection component to improve the sealing performance of the connection.

[0012] Optionally, the air conditioning box body includes a vibration reduction device for reducing vibration and noise during operation of the blower.

[0013] Optionally, the air conditioning box body also includes an airflow adjustment device for adjusting the size and direction of the airflow output by the blower.

[0014] An automobile air conditioning system further comprises a control system and a power supply system. The control system is used to control the operating parameters of a blower, and the power supply system provides electric energy for the blower.

[0015] Optionally, the control system can achieve precise control of the blower operating parameters through a preset program or remote instructions, including but not limited to parameters such as wind speed, wind direction and working time.

[0016] Optionally, the automobile air conditioning system also includes a fault diagnosis system for monitoring the operating status of the blower in real time and issuing an alarm or automatically performing fault processing when a fault occurs.

[0017] The beneficial effects of the utility model are:

[0018] This solution uses modular design to integrate the main components of the blower into an independent module, so that the entire blower can be installed and removed as a whole. This design greatly simplifies the installation and removal process. Technicians only need to remove a few connectors to easily complete the replacement or maintenance of the blower. At the same time, the modular design also improves the versatility and interchangeability of blower components and reduces spare parts inventory costs.

[0019] In addition, this solution also uses easy-to-remove fasteners and seals, which do not require special tools during disassembly, reducing the difficulty of disassembly and the risk of damage. At the same time, these components also have good sealing performance, ensuring the stability and reliability of the blower during operation.

[0020] In summary, this solution solves the technical pain points of traditional blowers in installation and disassembly through its unique design and structure, and improves the overall performance and after-sales service efficiency of automotive air-conditioning systems. This innovative design brings a more efficient and convenient solution to the automotive industry, meeting consumers' demand for high-quality automotive air-conditioning systems. This solution better solves the problems of large vibration, high noise, difficult after-sales disassembly, and process feasibility of the center-mounted double-layer flow, reduces the labor cost of after-sales maintenance, and improves the productivity of the product. At the same time, it solves the problems of vibration and noise, and improves the comfort of drivers and passengers.
