[0001] This utility model relates to the field of bus air conditioning technology, specifically a modular and easy-to-maintain bus air conditioner. Background Technology

[0002] Buses are mostly used for passenger transport. To improve the comfort of buses, they are equipped with air conditioning. However, bus air conditioners are usually large and require multiple bolts for fixing. Therefore, installation and disassembly are time-consuming and laborious, making it difficult for one person to complete the maintenance.

[0003] Existing bus air conditioners are very inconvenient to dismantle and maintain, and due to the large interior space of buses, existing air conditioners are unable to provide cooling and heating. Therefore, they do not meet current needs. To address this, we propose a modular and easy-to-maintain bus air conditioner. Utility Model Content

[0004] The purpose of this utility model is to provide a modular and easy-to-maintain bus air conditioner to solve the problems mentioned in the background art, such as the inconvenience of disassembling and maintaining bus air conditioners, and the difficulty of existing air conditioners to cope with the large interior space of buses in terms of cooling and heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular and easy-to-maintain bus air conditioner, comprising an air outlet housing, an air conditioning housing at the top of the air outlet housing, two condensers on one side inside the air conditioning housing, two condenser fans at the top of each condenser, a compressor on one side of each condenser, two evaporators on the other side inside the air conditioning housing, two evaporator fans on the outer side of each evaporator, a fresh air exchange module on the outer side of the two evaporator fans located at the outermost edge inside the air conditioning housing, a connecting pipe connected to the output end of the compressor, a controller on the outer side of each condenser, and an air outlet filter on the surface of the air outlet housing.

[0006] Preferably, both the air conditioner housing and the air outlet housing have multiple mounting holes on their surfaces, and the air conditioner housing and the air outlet housing are connected by bolts inserted into the internal threads of the mounting holes.

[0007] Preferably, a fan end cover is provided inside the air conditioner housing near the condenser. The fan end cover is connected to the air conditioner housing by bolts and threads, and the controller and condenser are both sealed inside the fan end cover.

[0008] Preferably, two mounting plates are rotatably mounted on both sides of the air outlet housing, and two hinges are provided on both sides of the air outlet housing near the mounting plates. A rotating shaft is fixedly mounted on both ends of the mounting plate, and the rotating shaft is rotatably engaged into the interior of the hinge.

[0009] Preferably, an arc-shaped plate is fixedly installed at the bottom of each mounting plate, and the surface of each arc-shaped plate is provided with a vertical through hole. A movable pin is movably installed on the surface of each mounting plate, and the movable pin extends through the interior of the mounting plate to the bottom position of the mounting plate. The movable pin is movably engaged into the interior of the vertical through hole.

[0010] Preferably, each of the mounting plates has a spring groove inside, and an L-shaped limiting rod is slidably installed inside each spring groove. Each spring groove has a sliding groove at its top. One end of the L-shaped limiting rod is movably inserted into the sliding groove. The outer surface of the movable pin has a limiting hole, and the other end of the L-shaped limiting rod is movably inserted into the limiting hole.

[0013] 1. This utility model, through the cooperation of the mounting plate and the movable pin, allows the device to be used by placing the air outlet housing on the top of the bus. The mounting plate is then rotated to align with the top of the bus, allowing the arc-shaped plate to be inserted into a pre-set arc-shaped groove on the bus surface, thus installing the air outlet housing. Subsequently, the movable pin is inserted from the surface of the mounting plate into the interior of the bus top, passing through a vertical through-hole in the surface of the arc-shaped plate to fix it in place. Simultaneously, an L-shaped limiting rod further secures the movable pin. At this point, the mounting plate... It is not possible to directly rotate the outer surface of the air outlet housing to fix the air outlet housing to the bus. When it is necessary to maintain the internal parts of the air outlet housing and the air conditioning housing, first pull the L-shaped limit rod along the direction of the sliding groove to release the L-shaped limit rod from the limit of the movable pin. Then the movable pin can be pulled out from the surface of the mounting plate. Then the mounting plate can be rotated to release the limit between the arc plate and the top of the bus. This allows the air outlet housing and the air conditioning housing to be easily removed and taken off, avoiding the situation where traditional air conditioners need to use multiple bolts to fix them to the bus.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This utility model provides an embodiment of a modular and easy-to-maintain bus air conditioner, including an air outlet housing 2, an air conditioner housing 1 at the top of the air outlet housing 2, two condensers 11 on one side inside the air conditioner housing 1, two condenser fans 3 at the top of each condenser 11, a compressor 9 on one side of each condenser 11, two evaporators 6 on the other side inside the air conditioner housing 1, two evaporator fans 8 on the outer side of each evaporator 6, and a fresh air exchange module 7 on the outer side of the two evaporator fans 8 located at the outermost edge inside the air conditioner housing 1. The output end of the compressor 9 is connected to a connecting pipe 12, a controller 10 is provided on the outer side of each condenser 11, and an air outlet filter 4 is provided on the surface of the air outlet housing 2.

[0023] By installing two independently operating compressors 9, evaporators 6 and condensers 11 inside the air conditioning housing 1, and through good spatial arrangement and piping, the cooling and heating effects and the range of cooling and heating of this device are improved, making it convenient for use in buses with large interior spaces.

[0024] Both the air conditioner housing 1 and the air outlet housing 2 have multiple mounting holes 5 on their surfaces. The air conditioner housing 1 and the air outlet housing 2 are connected by bolts inserted into the internal threads of the mounting holes 5.

[0025] A fan end cover is provided inside the air conditioner housing 1 near the condenser 11. The fan end cover is connected to the air conditioner housing 1 by bolts and threads. The controller 10 and the condenser 11 are both sealed inside the fan end cover.

[0026] Two mounting plates 13 are rotatably mounted on both sides of the air outlet housing 2. Two hinges 14 are provided on both sides of the air outlet housing 2 near the mounting plates 13. A rotating shaft 16 is fixedly mounted on both ends of the mounting plates 13. The rotating shaft 16 is rotatably inserted into the interior of the hinge 14.

[0027] An arc-shaped plate 18 is fixedly installed at the bottom of each mounting plate 13. The surface of the arc-shaped plate 18 is provided with a vertical through hole 19. A movable pin 15 is movably installed on the surface of each mounting plate 13. The movable pin 15 extends through the interior of the mounting plate 13 to the bottom position of the mounting plate 13. The movable pin 15 is movably engaged into the interior of the vertical through hole 19.

[0028] With the cooperation of the mounting plate 13 and the movable pin 15, the device can be used by placing the air outlet housing 2 on the top of the bus, rotating the mounting plate 13 to make it fit against the top of the bus, thereby inserting the arc-shaped plate 18 into the pre-set arc-shaped groove on the surface of the bus, thus installing the air outlet housing 2. Then, the movable pin 15 is inserted from the surface of the mounting plate 13 into the interior of the top of the bus, so that the movable pin 15 passes through the vertical through hole 19 on the surface of the arc-shaped plate 18, thereby fixing the arc-shaped plate 18. At the same time, the movable pin 15 is fixed by the L-shaped limiting rod 22. At this time, the mounting plate 13... 3. It is not possible to directly rotate the outer surface of the air outlet housing 2 to fix the air outlet housing 2 to the bus. When it is necessary to maintain the internal parts of the air outlet housing 2 and the air conditioning housing 1, first pull the L-shaped limit rod 22 along the direction of the sliding groove 23 to release the L-shaped limit rod 22 from the limit of the movable pin 15. Then the movable pin 15 can be pulled out from the surface of the mounting plate 13. Then the mounting plate 13 can be rotated to release the limit between the arc plate 18 and the top of the bus. Thus, the air outlet housing 2 and the air conditioning housing 1 can be easily removed and taken off, avoiding the situation where traditional air conditioners need to use multiple bolts to fix them to the bus.

[0029] The mounting plate 13 is provided with spring grooves 20 inside each spring groove 20. An L-shaped limiting rod 22 is slidably installed inside each spring groove 20. A sliding groove 23 is provided at the top of each spring groove 20. One end of the L-shaped limiting rod 22 is movably inserted into the sliding groove 23. A limiting hole 17 is provided on the outer surface of the movable pin 15. The other end of the L-shaped limiting rod 22 is movably inserted into the limiting hole 17.

[0030] A compression spring 21 is movably installed between the L-shaped limiting rod 22 and the inside of the spring groove 20. One end of the compression spring 21 is connected to the L-shaped limiting rod 22, and the other end of the compression spring 21 is connected to the inner wall of the spring groove 20.

[0031] When using this modular and easily maintainable bus air conditioner, the air outlet housing 2 is placed on top of the bus. The mounting plate 13 is then rotated to align with the bus top, allowing the arc-shaped plate 18 to be inserted into a pre-designed arc-shaped groove on the bus surface, thus installing the air outlet housing 2. Subsequently, the movable pin 15 is inserted from the surface of the mounting plate 13 into the interior of the bus top, passing through the vertical through hole 19 on the surface of the arc-shaped plate 18 to secure it. Simultaneously, the movable pin 15 is fixed by the L-shaped limiting rod 22. At this point, the mounting plate 13 cannot be directly... Rotating the outer surface of the air outlet housing 2 secures the air outlet housing 2 to the bus. When maintenance is required on the internal parts of the air outlet housing 2 and the air conditioning housing 1, the L-shaped limiting rod 22 is first pulled along the direction of the sliding groove 23 to release the limiting of the movable pin 15. The movable pin 15 can then be pulled out from the surface of the mounting plate 13. The mounting plate 13 can then be rotated to release the limiting of the arc plate 18 to the top of the bus. This allows the air outlet housing 2 and the air conditioning housing 1 to be easily removed, avoiding the need for multiple bolts to secure the air conditioner to the bus as is common in traditional air conditioners.

[0032] By installing two independently operating compressors 9, evaporators 6 and condensers 11 inside the air conditioning housing 1, and through good spatial arrangement and piping, the cooling and heating effects and the range of cooling and heating of this device are improved, making it convenient for use in buses with large interior spaces.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
