Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to an air conditioning compressor installation structure for new energy vehicles. Background Technology

[0002] In existing technologies, new energy refrigerated trucks typically require an air conditioning compressor for refrigerating the cargo box. The air conditioning compressor is usually driven by a drive motor. However, the drive motor needs to drive the air conditioning compressor via a belt. Therefore, the installation of the air conditioning compressor needs to take into account the belt tension. If the belt is too tight, the air conditioning compressor is not easy to install; if the belt is too loose, it is not easy to drive the air conditioning compressor to work. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide an air conditioning compressor installation structure for new energy vehicles. The air conditioning compressor is set on an adjustment bracket, and the tension of the belt can be adjusted by adjusting the relative adjustment of the adjustment bracket. It can also prevent the air conditioning compressor from shaking, making it more stable during use.

[0004] This utility model discloses an air conditioning compressor mounting structure for a new energy vehicle, including an assembly frame. The assembly frame is equipped with a drive motor, a first air conditioning compressor, and a first belt. The output shaft of the drive motor is equipped with a first drive wheel that rotates synchronously with it. It also includes a first rotating wheel on the first air conditioning compressor that is linked and cooperates with the first drive wheel. The first belt is sleeved on the first drive wheel and the first rotating wheel. The characteristic feature is that the drive motor or the assembly frame is equipped with a first adjusting frame. The first adjusting frame includes a first mounting plate that can slide relative to the drive motor and a first push rod that drives the first mounting plate to slide. The first mounting plate is equipped with a first elongated slot. The first push rod is threaded into the first mounting plate and is arranged along the length direction of the first elongated slot. It also includes a first locking bolt that passes through the first elongated slot and is threaded into the drive motor or the assembly frame. The bottom of the first push rod can abut against the drive motor or the assembly frame.

[0005] Using the above technical solution, a relatively loose first belt can be used to install the first air conditioning compressor. After the first air conditioning compressor is installed, the first push rod rotates and lifts the first mounting plate through the threaded engagement, thereby tensioning the first belt. After adjustment, the first mounting plate is locked by the first locking bolt passing through the first long slot hole, thereby preventing it from slipping later. After long-term use, the first belt will become relatively loose again. At this time, the first locking bolt can be loosened and the tension can be adjusted by pushing with the first push rod.

[0006] A further feature of this invention is as follows: the first air conditioning compressor is located on top of the drive motor, and the first elongated slot is arranged vertically. A second air conditioning compressor is located on one side of the drive motor on the mounting frame. A second rotating wheel is rotatably mounted on the second air conditioning compressor. A second drive wheel is mounted on the drive motor and is linked to the second rotating wheel. A second belt is fitted on the second rotating wheel and the second drive wheel. A second adjusting frame is mounted on the drive motor or the mounting frame. The second adjusting frame includes a second mounting plate that can slide laterally relative to the drive motor and a second push rod that drives the second mounting plate to slide. A second elongated slot is provided on the drive motor or the mounting frame. The second elongated slot is arranged horizontally. The second push rod is threadedly engaged with the second mounting plate and is arranged along the length of the second elongated slot. It also includes a second locking bolt that passes through the second elongated slot and is threadedly engaged with the second mounting plate. The bottom of the second push rod can abut against the drive motor or the mounting frame.

[0007] The above technical solution employs multiple air conditioning compressors, one of which can control the temperature of the cab, main drive motor, and battery pack, while the other is suitable for the temperature of the cargo box in refrigerated trucks. A second adjustment bracket is used to adjust the tension of the second belt, thereby preventing the second belt from slipping and facilitating the installation of the second air conditioning compressor. The specific adjustment method is to loosen the second locking bolt and rotate the second push rod. After adjustment, the second locking bolt is rotated to lock the second mounting plate.

[0008] A further feature of this invention is that a magnetic assemblies are connected to the input shafts of both the first and second air conditioning compressors. The magnetic assemblies include a coil and a clutch disc. The clutch disc is located on the input shaft of the corresponding air conditioning compressor and rotates synchronously with it. The inner sides of both the first and second rotating wheels are provided with assembly cavities. The coil is located on the corresponding air conditioning compressor and is partially located in the assembly cavity. The clutch disc is provided with magnetic plates.

[0009] Using the above technical solution, when the coil is energized, the corresponding rotating wheel will generate magnetic force, thereby attracting the magnetic plate on the clutch disc. The magnetic attraction component can control the first and second rotating wheels to idle or work normally, so that one motor can drive two air conditioning compressors to work together or separately, making it more practical.

[0010] A further feature of this invention is that two first push rods are provided on opposite sides of the first air conditioning compressor, and two second push rods are provided on opposite sides of the second air conditioning compressor.

[0011] The above technical solution results in greater stability and better balance during adjustment. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0018] This utility model discloses an air conditioning compressor installation structure for a new energy vehicle, including an assembly frame 1. The assembly frame 1 is equipped with a drive motor 2, a first air conditioning compressor 3, and a first belt 4. The output shaft of the drive motor 2 is equipped with a first drive wheel 5 that rotates synchronously with it. It also includes a first rotating wheel 6 that is mounted on the first air conditioning compressor 3 and is linked to the first drive wheel 5. The first belt 4 is sleeved on the first drive wheel 5 and the first rotating wheel 6. In an embodiment of this utility model, the drive motor 2 or the assembly frame 1 is equipped with a first adjusting frame 7. The first adjusting frame 7 includes a first mounting plate 71 that can slide relative to the drive motor 2 and a first push rod 72 that drives the first mounting plate 71 to slide. The first mounting plate 71 is equipped with a first elongated slot 711. The first push rod 72 is threadedly engaged with the first mounting plate 71 and is arranged along the length direction of the first elongated slot 711. It also includes a first locking bolt 8 that passes through the first elongated slot 711 and is threadedly engaged with the drive motor 2 or the assembly frame 1. The bottom of the first push rod 72 can abut against the drive motor 2 or the assembly frame 1.

[0019] Using the above technical solution, the first air conditioning compressor 3 can be installed using a relatively loose first belt 4. After the first air conditioning compressor 3 is installed, the first push rod 72 rotates and lifts the first mounting plate 71 through the threaded engagement, thereby tensioning the first belt 4. After adjustment, the first mounting plate 71 is locked by the first locking bolt 8 passing through the first long slot 711, thereby preventing it from slipping later. After long-term use, the first belt 4 will become relatively loose again. At this time, the first locking bolt 8 can be released, and the tension can be adjusted by pushing with the first push rod 72.

[0020] The first air conditioning compressor 3 is located on top of the drive motor 2. The first elongated slot 711 is vertically oriented. A second air conditioning compressor 9 is located on one side of the drive motor 2 on the mounting frame 1. A second rotating wheel 10 is rotatably mounted on the second air conditioning compressor 9. A second drive wheel 20 is mounted on the drive motor 2 and is linked to the second rotating wheel 10. A second belt 30 is fitted onto the second rotating wheel 10 and the second drive wheel 20. A second adjusting frame 40 is mounted on the drive motor 2 or the mounting frame 1. The second adjusting frame 40 includes a second mounting plate 401 that can slide laterally relative to the drive motor 2 and a second push rod 402 that drives the second mounting plate 401 to slide. A second elongated slot 50 is located on the drive motor 2 or the mounting frame 1 and is horizontally oriented. The second push rod... The 402 thread fits on the second mounting plate 401 and is set along the length of the second long slot 50. It also includes a second locking bolt 60 that passes through the second long slot 50 and is threaded to the second mounting plate 401. The bottom of the second push rod 402 can abut against the drive motor 2 or the mounting bracket 1. Multiple air conditioning compressors are used, one of which can control the temperature of the cab, main drive motor and battery pack, and another can be used for the temperature of the cargo box of the refrigerated truck. The tension of the second belt 30 is adjusted by the second adjusting bracket 40, which can prevent the second belt 30 from slipping and facilitate the installation of the second air conditioning compressor 9. The specific adjustment method is to loosen the second locking bolt 60 and drive the second push rod 402 to rotate. After adjustment, the second locking bolt 60 is rotated to lock the second mounting plate 401.

[0021] Magnetic assemblies 70 are connected to the input shafts of the first air conditioning compressor 3 and the second air conditioning compressor 9. The magnetic assembly 70 includes a coil 701 and a clutch disc 702. The clutch disc 702 is located on the input shaft of the corresponding air conditioning compressor and rotates synchronously with it. The inner sides of the first rotating wheel 6 and the second rotating wheel 10 are provided with assembly cavities 80. The coil 701 is located on the corresponding air conditioning compressor and is partially located in the assembly cavity 80. The clutch disc 702 is provided with magnetic plates 90. When the coil 701 is energized, the corresponding rotating wheel will generate magnetic force, thereby attracting the magnetic plates 90 on the clutch disc 702. The magnetic assembly 70 can control the first rotating wheel 6 and the second rotating wheel 10 to idle or work normally (the normal working position is to drive the input shaft of the air conditioning compressor to rotate), so that one motor can drive two air conditioning compressors to work together or individually, which is more practical. Of course, the magnetic assembly 70 can also be omitted, in which case the first rotating wheel 6 and the second rotating wheel 10 can be located on the input shaft of the corresponding air conditioning compressor.

[0022] The first push rod 72 has two rods and is located on opposite sides of the first air conditioning compressor 3, and the second push rod 402 has two rods and is located on opposite sides of the second air conditioning compressor 9, which makes the adjustment more stable and the balance better.
