Description

Technical Field

[0001] This utility model relates to the field of bus parts technology, and in particular to an energy-saving and efficient bus air conditioning zoned air supply duct structure. Background Technology

[0002] As an important public transportation tool, the comfort of buses directly affects passengers' travel experience. Among them, the air conditioning system is a key device to ensure a comfortable environment inside the carriage. Typically, the bus air conditioning system uses a duct structure to deliver processed cold or hot air to various parts of the long and narrow carriage to regulate the temperature inside the vehicle.

[0003] In existing technology, the air outlet of an air conditioning unit is usually directly connected to the main air supply duct. Due to the high-speed rotation of the air conditioning fan impeller, the airflow blown out directly is often a turbulent airflow with uneven velocity and uncertain direction. After entering the main air duct, this turbulent airflow will cause severe mutual interference and friction with the duct wall and the airflow. This not only significantly increases the resistance of the airflow in the duct, forcing the fan to consume more electrical energy to overcome the resistance, but also easily generates greater wind noise due to the collision and eddy of the airflow, affecting the quietness of the ride.

[0004] In addition, the long and narrow passenger compartments of buses often result in uneven passenger distribution. For example, during off-peak hours, passengers tend to concentrate in the front or middle of the compartment. Traditional air supply ducts often use uniform air supply or simple manual air vent adjustment, which cannot intelligently and accurately distribute air volume according to the actual number of passengers in different areas of the compartment. This leads to a large amount of cooling or heating being continuously transported to almost unoccupied areas, resulting in significant and unnecessary energy waste, which contradicts the current social requirements for energy conservation and emission reduction. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an energy-saving and efficient bus air conditioning zoned air supply duct structure, aiming to improve the problems of low efficiency caused by turbulent airflow in the existing bus air conditioning ducts and energy waste caused by the inability to accurately control the air volume in zones.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving and efficient passenger car air conditioning zone air supply duct structure includes: a main air duct and an air supply branch pipe connected to the main air duct; a rectifier assembly disposed in the main air duct and an adjustment assembly disposed in the air supply branch pipe, the rectifier assembly including a fixed frame and an airflow rectifier mesh fixed in the fixed frame; a sliding groove is provided on the inner wall of the main air duct, and the fixed frame is detachably slidably connected in the sliding groove; The adjustment assembly includes a shaft rotatably connected inside the air supply branch pipe, with a first fixed shaft and a second fixed shaft fixedly connected to the outer wall of the shaft; the adjustment assembly also includes a second adjustment plate connected to the first fixed shaft and a first adjustment plate connected to the second fixed shaft; the adjustment assembly further includes a support frame fixed to the side wall of the air supply branch pipe, with a sliding groove provided in the support frame, and a sliding frame slidably connected in the sliding groove; an electric push rod is fixed on the support frame, and the output end of the electric push rod is connected to the sliding frame; a first fixed rod is connected to the side wall of the first fixed shaft, and a second limiting rod is connected to the side wall of the second fixed shaft; a groove is provided on the sliding frame, and the ends of the first fixed rod and the second limiting rod slide within the groove.

[0007] Preferably, the rectifier assembly further includes a connecting block and a pull block, the connecting block being fixed to the side wall of the fixed frame, and the pull block extending to the outside of the main air duct and connecting to the connecting block.

[0008] Preferably, the rectifier assembly is located in the initial section of the main air duct near the air outlet of the upstream air conditioning unit.

[0009] Preferably, the air supply branch pipe is connected to the bottom of the main air duct via a sealed flange interface.

[0010] Preferably, the two ends of the shaft are rotatably connected to the inner walls of the air supply branch pipe via bearings.

[0011] Preferably, the grooves on the sliding frame are two symmetrically arranged inclined straight grooves.

[0012] Preferably, the first adjusting plate and the second adjusting plate are fixed to the shaft in a V-shape symmetrically.

[0013] In one specific implementation, the first adjusting plate and the second adjusting plate are an integral structure and are fixed together on the shaft.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a detachable rectifier component in the main air duct, the airflow rectifier mesh in the rectifier component can sort out the airflow, which solves the problems of disordered state and uneven flow velocity when the air conditioning airflow directly enters the main air duct in the prior art, resulting in high wind resistance, high energy consumption and high noise. It achieves the technical effects of reducing wind resistance, reducing energy loss, improving air supply efficiency and reducing operating noise. At the same time, its detachable structural design also greatly facilitates later cleaning and maintenance.

[0015] 2. In this utility model, by setting an adjustment component driven by an electric push rod in each air supply branch pipe, and using the linkage mechanism of sliding frame, groove and connecting rod to precisely control the opening and closing angle of the adjustment plate, the problem of existing bus air conditioning ducts being unable to independently regulate the air volume of different areas, resulting in the inability to supply air on demand and causing serious energy waste, is solved. The technical effect of independently and precisely controlling the air volume of each zone is achieved, which can adapt to the actual needs of different areas and realize on-demand air supply, thereby significantly avoiding energy waste.

A sliding groove 405 is provided; a sliding frame 404 is slidably connected in the sliding groove 405; an electric push rod 406 is fixed on the support frame 403, and the output end of the electric push rod 406 is connected to the sliding frame 404; a first fixed rod 411 is connected to the side wall of the first fixed shaft 408, and a second limiting rod 412 is connected to the side wall of the second fixed shaft 409; a groove 410 is provided on the sliding frame 404, and the ends of the first fixed rod 411 and the second limiting rod 412 slide in the groove 410. The support frame 403 of the adjustment component 4 is fixed to the side wall of the air supply branch pipe 2. An electric push rod 406, which serves as a power source, is fixed on the support frame 403. A sliding groove 405 is provided inside the support frame 403. A sliding frame 404 is slidably connected in the sliding groove 405, and the sliding frame 404 is connected to the output end of the electric push rod 406. The shaft 407 is rotatably connected to the inside of the air supply branch pipe 2. The two ends of the shaft 407 are rotatably connected to the opposite inner walls of the air supply branch pipe 2 through bearings. A first fixed shaft 408 and a second fixed shaft 409 are fixedly connected to the outer wall of the shaft 407. A first fixed rod 411 is connected to the side wall of the first fixed shaft 408, and a second limiting rod 412 is connected to the side wall of the second fixed shaft 409. In the assembled state, the sliding frame 404 has a groove 410, which is two symmetrically arranged inclined straight grooves. The ends of the first fixing rod 411 and the second limiting rod 412 slide in the corresponding grooves 410 respectively. This connecting rod and groove matching structure accurately converts the linear reciprocating motion generated by the electric push rod 406 driving the sliding frame 404 into the rotational motion of the shaft 407. To achieve airflow adjustment, the second adjusting plate 402 is connected to the first fixed shaft 408, and the first adjusting plate 401 is connected to the second fixed shaft 409. The first adjusting plate 401 and the second adjusting plate 402 are fixed to the shaft 407 in a V-shape. In another embodiment, the first adjusting plate 401 and the second adjusting plate 402 are an integral structure and are fixed to the shaft 407 together. This structure ensures that as the shaft 407 rotates, the opening and closing size of the first adjusting plate 401 and the second adjusting plate 402 can be controlled synchronously, thereby changing the ventilation cross-sectional area of ​​the air supply branch pipe 2. To facilitate disassembly and maintenance of the rectifier assembly 3, the rectifier assembly 3 also includes a connecting block 303 and a pull block 305. The connecting block 303 is fixed to the side wall of the fixing frame 302, and the pull block 305 extends to the outside of the main air duct 1 and connects to the connecting block 303. In order to rectify the airflow at the source of the main air duct 1 to obtain the best flow stabilization effect, the rectifier assembly 3 is set at the beginning section of the main air duct 1 near the air outlet of the upstream air conditioning unit. In order to ensure the firmness and airtightness of the connection between the main air duct 1 and the air supply branch pipe 2, the air supply branch pipe 2 is connected to the bottom of the main air duct 1 through a sealed flange interface. In order to reduce the frictional resistance when the shaft 407 rotates and improve the adjustment mechanism To ensure durability, the two ends of the shaft 407 are rotatably connected to the inner walls of the air supply branch pipe 2 via bearings. In order to stably and linearly convert the linear motion of the sliding frame 404 into the rotational motion of the shaft 407, the groove 410 on the sliding frame 404 consists of two symmetrically arranged inclined straight grooves. In order to form a symmetrical valve structure to achieve uniform adjustment of airflow, the first adjusting plate 401 and the second adjusting plate 402 are fixed to the shaft 407 in a V-shape. In order to simplify the component structure, improve the overall strength, and ensure that the two adjusting plates are completely synchronized in motion, the first adjusting plate 401 and the second adjusting plate 402 are an integral structure and are jointly fixed to the shaft 407.

[0020] Working principle: When the airflow processed by the air conditioning unit enters the main air duct 1, it first flows through the rectifier assembly 3 set in its initial section. During the process of the airflow passing through the airflow rectifier mesh 301, its original turbulent state is sorted into a uniform laminar flow. This process reduces the mutual interference and energy loss between airflows, reduces the wind resistance of the entire air duct system, and thus improves the overall efficiency of air circulation. When maintenance of the rectifier assembly 3 is required, by pulling the pull block 305, it drives the connecting block 303 and the fixing frame 302, and the airflow rectifier mesh 301 can be conveniently pulled out from the inside of the main air duct 1 along the slide groove 304.

[0021] When adjusting the airflow of the air supply branch pipe 2, the control system sends a command to drive the electric push rod 406 fixed on the support frame 403 to move. The output end of the electric push rod 406 pushes the sliding frame 404 to perform linear reciprocating motion in the sliding groove 405 of the support frame 403. During the movement of the sliding frame 404, the groove 410 inside it will push the first fixed rod 411 and the second limiting rod 412 that are slidably engaged with it to swing. Since the first fixed rod 411 and the second limiting rod 412 are respectively connected to the first fixed shaft 408 and the second fixed shaft 409, and the first fixed shaft 408 and the second fixed shaft 409 are both fixed on the shaft 407, the above swing is converted into the rotational motion of the shaft 407. As the shaft 407 rotates, the first adjusting plate 401 and the second adjusting plate 402 fixed on it also rotate, changing their opening and closing angles, thereby accurately controlling the airflow through the air supply branch pipe 2, realizing on-demand zoned air supply and avoiding energy waste.
