[0029] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0032] HVAC outdoor units are usually placed outdoors and their location needs to be adjusted in some cases. When the surrounding environment of the HVAC outdoor unit changes, such as the construction of a new building or the presence of obstacles in a previously open area, affecting the ventilation of the HVAC outdoor unit and causing poor airflow, the direction may need to be adjusted to ensure the normal operation of the HVAC outdoor unit. If the noise generated by the HVAC outdoor unit during operation affects the lives of surrounding residents, adjusting the direction of the HVAC outdoor unit may redirect the noise away from sensitive areas.

[0033] The technical solution in this embodiment effectively solves the problem that when the position of an existing HVAC outdoor unit needs to be adjusted due to building obstruction or other reasons, it is generally necessary for staff to disassemble the entire fixed frame, readjust the position, and then reinstall it. This process is complicated, labor-intensive, and inefficient in adjusting the HVAC outdoor unit.

[0034] This embodiment provides an outdoor unit for engineering HVAC systems with an adjustable opening orientation, such as... Figure 1 As shown, the system includes a chassis 1 (i.e., an outdoor unit for HVAC), on which an adjustment mechanism is installed. The adjustment mechanism includes a base plate 2, a U-shaped frame 23, a motor 3, a threaded rod 31, and a rack 4. The U-shaped frame 23 has an opening facing the base plate 2 and is vertically fixedly installed on the base plate 2. The U-shaped frame 23 has space to accommodate the chassis 1. A mounting plate 25 is vertically installed on one side of the base plate 2, and a fixing block 26 is installed on the opposite side. A threaded groove 42 is opened through the side end of the rack 4, and the threaded rod 31 is threadedly rotatably installed on the inner side wall of the threaded groove 42. The motor 3 is fixedly installed on one side of the mounting plate 25. One end of the threaded rod 31 is connected to the output end of the motor 3, and the other end is rotatably installed on the fixing block 26. A rotating shaft 13 is fixedly installed at the bottom of the chassis 1, and the bottom end of the rotating shaft 13 is rotatably installed on the base plate 2. A gear 14 is fixedly installed at the circumferential end of the rotating shaft 13, and the gear 14 meshes with the rack 4.

[0035] In a specific implementation, the base plate 2 is used to mount other components and provide support for the entire adjustment mechanism.

[0036] In specific implementation methods, such as Figure 2 As shown, the U-shaped frame 23 serves to support and fix related components. A mounting groove 21 is provided through the top of the U-shaped frame 23, and a scale plate 22 is fixedly mounted on the top surface of the U-shaped frame 23. The scale plate 22 has an arc-shaped structure, and the scale plate 22 is installed avoiding the mounting groove 21. Figure 3As shown, a drive shaft 11 is fixedly installed on the top of the chassis 1. The drive shaft 11 extends out from the mounting slot 21. A pointer 12 is fixedly installed on the upper end of the drive shaft 11. When the chassis 1 is adjusted, the drive shaft 11 on the chassis 1 will rotate. The rotation of the drive shaft 11 will drive the pointer 12 to rotate. When the pointer 12 rotates, it will indicate different values ​​on the scale 22, making it convenient for the user to observe the rotation angle of the chassis 1.

[0037] In a specific implementation, the centers of the rotating shaft 13 and the transmission shaft 11 are on a straight line.

[0038] In a specific embodiment, a rotating shaft 13 is fixedly installed at the bottom of the chassis 1. The rotating shaft 13 is rotatably mounted on the base plate 2. A gear 14 is fixedly installed at the circumferential end of the rotating shaft 13. The rotation of the gear 14 will drive the chassis 1 on the rotating shaft 13 to rotate, thereby realizing the adjustment of the orientation angle of the chassis 1.

[0039] In specific implementation methods, such as Figure 4 As shown, a movable groove 24 is provided on the base plate 2, and a fixing block 26 is also fixedly installed on the base plate 2. The fixing block 26 is arranged opposite to the mounting plate 25, and the movable groove is opened on the mounting plate between the fixing block 26 and the mounting plate 25. A threaded rod 31 is fixedly installed on the output end of the motor 3. When adjusting the orientation of the chassis 1, the user can start the motor 3 through a remote infrared remote control device. The infrared remote control device has specific control buttons, and the remote control contains an infrared emitting circuit. When the user presses the button, the circuit will generate a corresponding infrared signal according to a preset code. The motor 3 integrates an infrared receiving module, a microcontroller (MCU), and a motor drive module. The infrared receiving module receives infrared signals emitted by the remote control. The microcontroller (MCU) receives the signals output by the infrared receiving module, decodes them, and identifies the user's operation commands. The motor drive module has a power input pin, a control signal input pin connected to the output pin of the microcontroller, and a motor connection pin connected to the positive and negative terminals of the motor 3. It can amplify the control signals output by the microcontroller and provide sufficient drive current to the motor 3, thereby driving the threaded rod 31 at the output end of the motor 3 to rotate in the forward or reverse direction, thereby driving the rack 4 to move. The rack 4 meshes with the gear 14 to achieve the steering effect of the chassis 1.

[0040] In a specific embodiment, the rack 4 is smaller than the threaded rod 31. The threaded rod 31 is rotatably mounted through the inner wall of the fixed block 26. A slide rod 41 is fixedly mounted at the bottom of the rack 4. The slide rod 41 is slidably mounted on the inner wall of the movable groove 24. A threaded groove 42 is opened through the side end of the rack 4. The threaded rod 31 is rotatably mounted on the inner wall of the threaded groove 42. The rack 4 and the gear 14 mesh. The rotation of the threaded rod 31 through the threaded groove 42 will drive the rack 4 to slide on the base plate 2. The rack 4 drives the slide rod 41 to slide in the movable groove 24. The movable groove 24 guides the slide rod 41 and the rack 4. The movement of the rack 4 will drive the gear 14 to rotate.

[0041] Working principle of this utility model:

[0042] During the installation of the outdoor unit, the HVAC outdoor unit casing is placed on a specially designed base plate, ensuring a secure connection between the casing and the base plate. A movable groove is pre-set on the base plate, and a structure with a graduated dial is installed, positioned for easy observation. Simultaneously, the drive shaft is connected to the casing, with a pointer installed at one end of the drive shaft, aligning with the graduated dial for subsequent observation of angle changes. The motor is installed at the corresponding position on the base plate, and its output end is connected to a threaded rod. A rack is installed on the base plate, engaging with the threaded rod through a threaded groove, and a sliding rod is connected to the rack, positioned within the movable groove to ensure smooth sliding of the rack on the base plate. A rotating shaft is connected to the bottom of the casing, meshing with the gear on the rack to form a complete angle adjustment transmission mechanism. After completing the above installation, the motor is tested using a remote infrared control device. The motor is started, driving the threaded rod to rotate forward or backward, observing the rack's sliding on the base plate and the guiding effect of the sliding rod within the movable groove.

[0043] When in use, the chassis 1 is usually placed outdoors. For example, in the HVAC systems of some small commercial buildings or multi-story residential buildings, chassis 1 is often installed on the exterior wall of the lower floors of the building, which facilitates installation, maintenance and repair. Many large commercial buildings, industrial plants or large public buildings such as shopping malls, factories, stadiums, etc., due to their large internal space and high air conditioning load, will place chassis 1 on the flat roof. In some small buildings or places with high requirements for the building's appearance, if a pitched roof is used, chassis 1 may be placed in the attic space of the pitched roof or on the outside of the gable wall. In some cases, the position needs to be adjusted. When the surrounding environment of chassis 1 changes, such as the construction of a new building in a previously open area or the presence of obstacles... Obstructions have affected the ventilation of chassis 1, causing poor airflow. To ensure the normal operation of chassis 1, its orientation may need to be adjusted. Alternatively, if the noise generated by chassis 1 during operation affects the lives of surrounding residents, adjusting the orientation of chassis 1 may redirect the noise away from sensitive areas. When adjusting the orientation of chassis 1, the user can start motor 3 via a remote infrared control device, thereby driving the threaded rod 31 at the output end of motor 3 to rotate forward or backward. The rotation of threaded rod 31, through threaded groove 42, will drive rack 4 to slide on base plate 2. Rack 4 will drive slide rod 41 to slide within movable groove 24. Movable groove 24 guides slide rod 41 and rack 4. The movement of the gear 14 causes it to rotate, which in turn causes the chassis 1 on the rotating shaft 13 to rotate, thus adjusting the orientation angle of the chassis 1. Adjusting the chassis 1 causes the drive shaft 11 on the chassis 1 to rotate, which in turn causes the pointer 12 to rotate. The pointer 12 then indicates different values ​​on the dial 22, allowing the user to observe the rotation angle of the chassis 1. When the existing chassis 1 is obstructed by buildings or other structures, and its position needs to be adjusted, it generally requires workers to disassemble the entire fixed frame, readjust its position, and then reinstall it. This process is cumbersome, labor-intensive, and inefficient in adjusting the chassis 1. This device, through the cooperation of a motor 3, a threaded rod 31, a rack 4, and a gear 14, allows for easy adjustment of the angle of the chassis 1. Simply start the motor 3 remotely to rotate the threaded rod 31, and the rack 4 and gear 14 will adjust the angle of the chassis 1. This convenient operation eliminates the need for manual disassembly and installation, improving efficiency. Furthermore, the device incorporates a drive shaft 11, a pointer 12, and a dial 22. Adjusting the angle of the chassis 1 simultaneously rotates the pointer 12 on the drive shaft 11, allowing for direct observation of the chassis 1's rotation angle. This facilitates more precise and faster adjustment by the user.

[0044] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
